How to donate blood for TTG to women. How to properly take a test for TSH, T4 and T3. A decrease in the indicator can be observed when

Hormones are substances that can regulate the activities of the entire body. Blood tests help monitor their concentration and can indicate various disorders in the body.

A study of the level of thyroid-stimulating hormone gives an understanding of the rate of functioning of the endocrine system as a whole.

From this article you will learn:

The stages of preparation for analysis are no different for men and women, because everything is the same for them. Indicators may not be entirely correct in the following situations:

  1. the patient is pregnant- always elevated and this is normal;
  2. the patient is already elderly- thyroid-stimulating hormones in such people are normally low.

Preparation for the TSH test is necessary to minimize distortion of the test results. It consists of several key aspects:

  • At least 3 days before the test, you need to eliminate the consumption of iodine-containing foods, medications, vitamins, and not eat aggressive foods (fatty, salty, very sweet (!!!), spicy).
  • One day before donating blood, do not smoke, do not go to the gym (only light physical activity is allowed) and do not drink alcohol
  • (the interval between the last meal and the collection of biomaterial should be at least 12 hours). For drinks, you can only have a little regular still water.
  • It is better to undergo the procedure in the morning.
  • A month before the test, you need to stop taking hormone replacement therapy (T3, T4, TSH). Moreover, if it is impossible to stop treatment (only according to the conclusion of an endocrinologist), this point is skipped.
  • 3-4 days before donating the biomaterial, the patient should try to protect himself from stress.
  • Immediately before the test, it is better to just sit quietly, not run or get nervous.
  • If possible, stop taking combined oral contraceptives, aspirin, corticosteroids, and strong sedatives. If this is not possible, you must inform the specialist who is conducting the analysis about taking medications.

Submission procedure

The procedure, as is already known, is carried out mainly in the morning. For analysis, a specialist takes a small amount venous blood. This happens as follows:

  • a tourniquet is applied to the forearm;
  • the surface of the skin is wiped with an antiseptic;
  • Blood is taken from the saphenous vein using a syringe.

The procedure is practically painless. As for the cost of the analysis, it is not very cheap. On average, in private laboratories its price is about 5,000 rubles, and the concentration is also analyzed.

What influences the result of the analysis?

The concentration of thyroid-stimulating hormone is not a constant value. It may change when:

  • systematic fasting;
  • severe psycho-emotional disorders;
  • intense sports activities;
  • pregnancy;
  • protein-free diet;
  • constant drinking of alcohol and smoking;
  • iodine deficiency.

When to donate blood for TSH? — indications for analysis

  • there are enlargements in the thyroid gland;
  • when the lobes of the gland are displaced to the left or right;
  • when palpating, nodes are felt;
  • there is a feeling of lack of air, squeezing in the throat, discomfort appears when consuming liquids and food;
  • a person constantly feels unwell, is in a bad mood, has constant weakness, swelling, hair loss, weight loss for no reason (appetite is normal);
  • The patient has a constantly rapid heartbeat.

The patient needs to be examined by a doctor so that he can identify these indirect symptoms of a malfunction of the endocrine system. You should also take a TSH test when the patient has a history of:

  • renal failure;
  • infertility;
  • toxic goiter;
  • obesity or vice versa dystrophy;
  • mental pathologies;
  • cervical osteochondrosis;
  • intracranial pressure;
  • hypertensive crisis;
  • thyroid adenoma;
  • cirrhosis of the liver;
  • severe lead poisoning;
  • pituitary tumor.

Also, this test can be prescribed to a patient if he is undergoing hormone replacement therapy with L-thyroxine, with special attention paid not to TSH, but to triiodothyronine.

TSH in pregnant women

Pregnancy is one of the periods when it is necessary to donate blood for TSH. This analysis is included in the list of mandatory tests and is prescribed by an endocrinologist.

During pregnancy, women experience a powerful hormonal surge; hormone levels must be constantly monitored. The analysis is carried out mainly in the first trimester of pregnancy.

This is justified by the fact that during this period the placenta is being formed and most of the mother’s biological resources are spent on the development of the baby. If the concentration of thyroid-stimulating hormone increases in pregnant women precisely in the 1st trimester, the risk of spontaneous abortion or the appearance of defects in the fetus increases.

In women in the early stages of pregnancy, the TSH concentration should normally be reduced. It ranges from 0.2 to 3.5 µIU/ml.

In some cases, the pituitary gland may stop working normally; this is usually observed in multiple pregnancies. In the second and third trimesters, thyroid-stimulating hormone levels may be elevated due to the effects of gestosis.

Research results and transcript

The analysis form usually has a whole column dedicated to reference values, where the concentration of glycoprotein in the blood is indicated. These values ​​do not always correspond to established standards, but do not be alarmed.

For example, if the patient is a child aged 2-11 weeks, a concentration of 10 µIU/ml will be normal for him. For adolescents under 14 years of age, the limit will be 5 µIU/ml.

With age, the reference indicator decreases in children; this phenomenon is normal. If a child has already reached the age of 15, the norm for him will be the same as for adults.

If a patient has a hyperconcentration of TSH (provided that this is not a pregnant woman), most likely he can be diagnosed with:

  • severe mental disorders;
  • pituitary tumor and thyrotropinoma;
  • Hashimoto's disease;
  • endemic goiter;
  • tumors in the lungs or chest;
  • malignant formations in the thyroid gland;
  • hypofunction of the thyroid gland;
  • hypothyroidism in the initial stages (1 and 2);
  • lead poisoning.

Also, this deviation can occur after undergoing drug therapy with antipsychotics, iodides or Prednisolone. The TSH ratio increases after hemodialysis.

The level of thyroid-stimulating hormone may decrease. This occurs due to such diseases:

  • hyperfunction of the thyroid gland;
  • various diseases of the pituitary gland (including those that can be caused by head injuries);
  • postpartum pituitary necrosis (Sheehan syndrome);
  • hyperthyroidism caused by pregnancy;
  • Ishchenko-Kushchenko syndrome;
  • mental disorders;
  • cachexia.

Some medications artificially reduce the concentration of thyroid-stimulating hormone: aspirin, heparin, anabolic steroids, glucocorticoids and others.

Often, among the many prescriptions of the attending physician, the patient has to see a referral for a TSH test. Leaving the health worker’s office and seeing the phrase “TSG blood test” on a piece of paper, the patient is puzzled. What is TSH? In what cases does a doctor prescribe a blood test for hormones? How to prepare for it? What do you need to know about decoding results? What to do if hormones are not normal?

The abbreviation TSH stands for thyroid-stimulating hormone, or thyrotropin. This hormone is produced by the pituitary gland, a gland located in the brain. Thyroid-stimulating hormone affects the functioning of the thyroid gland and promotes the production of its hormones: T3 and T4. These hormones are responsible for the activity of many systems in the body: cardiovascular, reproductive, gastrointestinal tract, many mental functions, and proper metabolism in humans. If the level of T3 and T4 in the body reaches a certain limit, the production of TSH is suppressed. Conversely, with a decrease in the production of T3 and T4, the concentration of thyrotropin increases. This is how the interconnected regulation of TSH and T4, T3 occurs in the body. That is why, along with a blood test for TSH, the patient often takes a test for the levels of hormones T3 and T4. The results obtained will help the therapist or endocrinologist create a more complete picture of the hormonal background of the body.

What is AT TPO?

Don't be intimidated by this intricate combination of letters. These are antibodies to thyroid peroxidase. This test is often prescribed in parallel with TSH. What it is? Thyroid cells normally continually produce the enzyme thyroid peroxidase. It is involved in the formation of T3 and T4. If everything is in order in the body, this is exactly what happens. But any immunity disorders lead to the fact that the enzyme thyroid peroxidase begins to be perceived as something hostile to the body. Antibodies are produced to it. Thus, the blood decoding will not be complete without taking into account the indicators AT TPO, T3 T4.

For what diseases is research required?

A blood test for thyrotropin levels will give the doctor valuable information about the condition of the thyroid gland. As a rule, a doctor carries out a referral for a blood test for hormones when there are suspicions of the following diseases:

  • hypothyroidism is a disease that develops when the thyroid gland does not produce enough hormones;
  • infertility;
  • decreased libido, impotence;
  • delayed mental and sexual development if a child is sent for analysis;
  • goiter - enlargement of the thyroid gland due to some reasons;
  • depression;
  • alopecia - progressive hair loss;
  • Heart arythmy;
  • hyperprolactinemia - increased levels of the hormone prolactin in the blood.

The patient may be referred for a TSH blood test in other situations: for example, in the case of previously identified hypothyroidism, it is advisable to conduct a TSH blood test at least 2 times a year. The patient will also have to undergo this test if the doctor wants to find out how effective the hormonal treatment he previously prescribed was.

How to prepare for the analysis?

For the study data to be reliable, the day before the patient should refrain from smoking, drinking alcohol and drinking large amounts of alcohol. physical activity. You should not indulge in fatty or spicy foods a day or two before your blood test. It is better to try to be in emotional balance at this time, since even minor stress can affect the results.

If the patient is already taking hormonal pills or, on the contrary, drugs that inhibit the production of hormones, the doctor will advise you to stop using them for 2 weeks before the test. If the attending physician did not consider it necessary to warn about this, then hormones should be taken according to the usual schedule.

You should be careful before taking a blood test and when taking vitamin complexes and iodine preparations. The fact is that iodine has direct impact on the functioning of the thyroid gland, because of this, the results of the study may be distorted.

Blood for analysis is given on an empty stomach before 10 am. Venous blood is taken for analysis.

Where to donate blood and how long to wait for results?

Blood tests for hormones are now done both in budget clinics and in paid hospitals. If a local doctor sends you for analysis, it is better to do it in the same clinic, because paid provision In this case, the service will not provide any advantages other than timing. IN paid clinics The analysis is ready the very next day; in state medical institutions, the blood test for hormone levels takes up to one week.

TSH transcript

Of course, many patients would like to know what the results of a TSH blood test mean. Decipher the results. What is the norm in deciphering the TSH blood test?

The norm of thyroid-stimulating hormone is different for each age category of patients. So, for newborns the norm for TSH is from 0.6 to 10 units per liter, for children from 2.5 months to 2 years the norm is from 4 to 7 units, for children from 2 to 5 years the norm is a TSH level of 4 - 6 units, for children over 14 years old and adults normal level TSH - from 0.4 to 4 units.

An increase in thyroid-stimulating hormone indicates that the thyroid gland is not as active as it should be normally. But you shouldn't always blame the thyroid gland alone. The TSH level also goes through the roof in other diseases:

  • somatic (literally means bodily diseases) and mental disorders;
  • adenoma (benign tumor) of the pituitary gland;
  • removed gallbladder;
  • lead poisoning of the body;
  • disorders of the adrenal glands.

An elevated TSH level does not always mean some serious pathology. Thus, an increase in the concentration of this hormone is often observed in pregnant women, in people constantly taking certain medications, and in patients in hemodialysis centers. In addition, increased levels of thyroid-stimulating hormone will be in patients who have undergone any surgery on the thyroid gland. Therefore, decoding the results of the analysis should take into account these circumstances.

A low TSH level indicates a highly active thyroid gland. A qualified physician will look at the description of TSH along with two other hormones: T3 and T4. There are options here. If TSH, T3, and T4 are all low, then there is reason to suspect the patient is developing hypothyroidism. If TSH is low and the other two hormones are high, this means the patient has a disease such as hyperthyroidism. In both cases, AT TPO should be normal.

A low TSH level when two other hormones are normal may indicate the following diseases:

  • severe mental disorder;
  • toxic goiter;
  • negative processes in the pituitary gland.

Neither an increased nor a decreased level of TSH in the blood should frighten the patient. It is worth remembering that the absolute norm in hormone levels is found only in a few. In any case, the most reliable transcript of a blood test can only be made by the attending physician. He will determine what is normal in the analysis and what is not normal, and will take into account many factors in total: the presence of other diseases, age, current or past thyroid diseases, symptoms that bother the patient. If the diagnosis is made by an endocrinologist, he will definitely pay attention to the patient’s thyroid gland: he will palpate this organ. The norm for it is normal sizes and no seals.

Since hormones play a very important role in the human body, you should not try to diagnose yourself. Moreover, you cannot prescribe treatment for yourself.

Only a qualified specialist can develop an adequate treatment system for any abnormalities associated with TSH.

Thyroid-stimulating hormone (TSH) is responsible for the proper functioning of the thyroid gland, stimulates the production of other gland hormones, which, in turn, affect the production of thyroid-stimulating hormone itself. This hormone is called a litmus test of human hormonal levels. What is thyroid-stimulating hormone and how to get tested for TSH?

What is thyroid-stimulating hormone

Thyroid-stimulating hormone (thyrotropin, thyrotropin, TSH) is a hormone produced by the anterior lobe of the pituitary gland. Thyrotropin receptors are located on the surface of the thyroid epithelium.

When thyrotropin acts on thyroid receptors, the production and activation of the hormone thyroxine is stimulated. In addition, TSH increases iodine consumption by thyroid cells. Thyrotropin is involved in the biosynthesis of the hormones thyroxine and triiodothyronine, which are the most important growth hormones.

The content of thyrotropin in the blood fluctuates throughout the day. The highest concentration of TSH in the blood occurs at two to three o'clock in the morning. By 6–8 a.m. the concentration of thyrotropin decreases slightly. The minimum values ​​of thyrotropin levels in the blood are observed at 17–19 hours. If a person is awake at night, his normal rhythm of secretion of this hormone is disrupted. In addition, the concentration of TSH in the blood becomes slightly higher with age, while the release of this hormone at night decreases. In pregnant women, the content of thyrotropin is reduced.

Indications for analysis

Blood test for TSH hormone prescribed in the following situations:

  • assessment of the thyroid gland;
  • diagnosis of thyroid dysfunction in newborns;
  • diagnosing female infertility and monitoring his treatment;
  • control of therapy for thyroid pathologies;
  • enlargement of the thyroid gland;
  • the presence of a symptom of hyperthyroidism (excess of thyroid hormones and iodine);
  • presence of symptoms of hypothyroidism (lack of thyroid hormones and iodine);
  • sexual delay and mental development in children;
  • idiopathic hypothermia (decrease in general body temperature below 35ºС);
  • myopathy (muscle disease), cardiac arrhythmias;
  • alopecia (diffuse hair loss);
  • depression;
  • decreased libido, impotence.

Preparing for analysis

The day before taking a TSH test, it is necessary to avoid drinking alcoholic beverages, smoking, physical activity, and emotional stress.

It is not recommended to eat for two to three hours before the test. You can only drink clean still water.

In agreement with your doctor, 48 hours before taking a TSH test, you need to avoid taking thyroid and steroid hormones.

Decoding

Thyroid-stimulating hormone levels vary according to different standards. Therefore, only the attending physician can decipher the analysis. In doing so, he will take into account individual characteristics the health status of each patient.

Reasons for deviations from the norm

Theriotropic hormone is the first to respond to changes in the condition of the thyroid gland, often when pathological symptoms have not yet appeared.

Elevated TSH levels occur in the following diseases and conditions:

  • severe mental and somatic illnesses;
  • development of tumors, in particular pituitary tumors;
  • adrenal insufficiency;
  • thyrotropinoma (pituitary adenoma);
  • thyroid hormone resistance syndrome;
  • syndrome of unregulated production of thyroid-stimulating hormone;
  • severe gestosis (late toxicosis) in pregnant women;
  • Hashimoto's thyroiditis, subacute thyroiditis;
  • primary and secondary hypothyroidism;
  • cholecystectomy (removal of the gallbladder);
  • hemodialysis;
  • taking certain medications, for example, Prednisolone, antipsychotics, iodides, beta-blockers;
  • lead poisoning.

A blood test for the hormone TSH may indicate a low level of this hormone in the following cases:

  • benign formation in the thyroid gland;
  • Plummer's disease (toxic thyroid adenoma);
  • decreased pituitary function;
  • toxic goiter;
  • hyperthyroidism in pregnancy;
  • pituitary injury;
  • cachexia (extreme exhaustion of the body);
  • excessive amounts of thyroid hormones as a result of self-medication with hormonal drugs;
  • Sheehan syndrome (a condition in a woman after childbirth in which pituitary cells die);
  • psychological stress;
  • diets, fasting.

TSH test during pregnancy

During pregnancy future mom must watch your hormonal levels and the functioning of the endocrine system. This is especially important before the tenth week of pregnancy. At this time, the child’s thyroid gland does not yet function independently, and the baby is completely dependent on maternal hormones. Therefore, at the slightest suspicion of a malfunction of the endocrine system during pregnancy, the doctor prescribes a TSH test.

The level of thyroid-stimulating hormone changes throughout pregnancy. It is different every trimester.

Typically, in pregnant women, the TSH level in the blood is moderately reduced. But, for example, during multiple pregnancy, the level of thyroid-stimulating hormone decreases significantly. Suppression of the level of this hormone in the blood is often accompanied by frequent vomiting.

Sometimes doctors prescribe their patients to take a blood test to determine the amount of thyroid-stimulating hormone. But not many people know how to donate blood for TSH and why it is needed, so they come to the laboratory unprepared, which is extremely undesirable. Therefore, the article provides information about the rules for passing this analysis and its interpretation.

What is TSH

The first step is to understand what the TSH hormone is responsible for and what it even is. So, thyroid-stimulating hormone belongs to the category of glycoproteins and is produced by the pituitary gland of the brain in order to neutralize the high content of the hormones T3 and T4 in the blood. And since these hormones play an important role in the functioning of the thyroid gland, a TSH test allows us to assess the functioning of the thyroid gland, as well as the entire endocrine system. When the level of thyroid-stimulating hormone in the body is normal, it means that everything is in perfect order with the endocrine system, but if it is greatly reduced or increased, then this may indicate the presence of pathological changes in the body. That’s why doctors prescribe a similar test for their patients in order to see this pathology in time and find out its cause, because if the level of TSH in the blood is not normalized, this can lead to a deterioration in the performance of the gastrointestinal tract, cardiovascular and reproductive systems.

What affects the level of TSH in the blood

Also, before we start figuring out how to properly donate blood for TSH, let’s find out what can generally affect the level of thyroid-stimulating hormone in the blood, as this will help you find out what not to do before the test, and what factor can lead to exceeding the norm of this hormone or its deficiency. So, TSH levels can be affected by:

  • pregnancy;
  • increased physical activity, which causes fatigue and increased blood pressure;
  • stress, anxiety, depression or fear;
  • any bad habits;
  • dietary food which involves avoiding protein consumption;
  • lack of iodine in the diet or its deficiency.

In addition, before donating blood for TSH, it is important to remember that the content of thyroid-stimulating hormone in the body fluctuates throughout the day. Its highest concentration in the blood is observed at 2-3 am, and then by 6-8 am it decreases slightly, and this time is ideal for taking the test. The lowest concentration of TSH in the blood is observed at 17-19 hours. However, if a person is awake at night, the rhythm of thyroid-stimulating hormone secretion is disrupted, so you must tell the doctor if you do not sleep at night, so that the analysis is not scheduled for the morning or the data received after it is deciphered differently.

Who is prescribed the analysis?

Now we have figured out what thyroid-stimulating hormone is, however, before we figure out how to take a blood test for TSH, let's figure out who can even be prescribed it. An endocrinologist may send a patient for testing if:

  • enlarged thyroid gland;
  • displacement of the thyroid lobe to the right or left;
  • patient complaints of tightness in the neck, inability to swallow food or liquid and lack of air;
  • causeless weight loss with good appetite;
  • patient complaints of weakness and constant swelling;
  • prolonged inability to get pregnant;
  • constant depression and rapid heartbeat;
  • disorders of the thyroid gland in newborns;
  • delayed mental and sexual development in children.

In addition, this analysis is prescribed to patients suffering from hypertensive crisis, renal failure, liver cirrhosis, mental pathologies, thyroid adenoma, toxic goiter, pituitary tumor, high intracranial pressure or cervical osteochondrosis.

Preparing to donate blood for TSH

Now that we know who is prescribed a TSH test, which allows us to find out its level in the body, let's figure out how to prepare for this test so that it allows the doctor to know the most complete picture of the patient's health status.

  1. One day before donating blood, you should stop smoking and drinking. alcoholic drinks.
  2. It is advisable to refrain from physical activity 24 hours before the analysis, which applies even to athletes who urgently need to stop training.
  3. A few days before donating blood, you need to stop eating too fatty and spicy foods.
  4. If the patient was taking hormonal medications or medications that suppressed hormones, then they should be stopped 2 weeks before the test.
  5. The day before donating blood, you should carefully take vitamins and any medications that contain iodine.
  6. You should donate blood on an empty stomach, that is, without having breakfast before it.
  7. If it so happens that blood is not donated early in the morning, then the test should be done no earlier than 3 hours after eating.

The process of donating blood for thyroid-stimulating hormone

Now that we have established what you should and should not do before donating blood for a TSH test, let's understand how the process works. Actually, there is nothing unusual in the analysis itself. You just need to come to a specialized clinic, since not every private or public laboratory can test for TSH, provide the nurse with a referral for the test, and then sit in the chair. The nurse will wipe the blood collection site with alcohol, and then use a sterile disposable syringe to take blood from the ulnar vein of the left or right arm. After this, a cotton swab is placed on the wound to stop the bleeding, you will need to bend your arm at the elbow and sit like that for about 15 minutes, and then you can safely go home.

Prescribing a blood test for TSH for pregnant women

Separately, we should talk about how to donate blood for TSH to pregnant women, because in this case there are some nuances in conducting the study. The fact is that while carrying a child, women experience a sharp increase in the level of hormones in the blood, so they are strongly recommended to visit an endocrinologist and take a TSH test.

The analysis should be carried out in the first trimester, when the placenta is just beginning to form and the fetus develops using the resources of the mother’s body. Therefore, it is necessary to find out what level of thyroid-stimulating hormone is in the body, because its deficiency can provoke spontaneous abortion or lead to the development of defects in the fetus.

However, there are cases when pregnant women in the second and third trimester were also sent for analysis in order to detect gestosis in time, which is indicated by high level TSH in the blood. The very preparation for the test and blood sampling from pregnant women occurs in exactly the same way as in standard cases.

Frequency of blood test for TSH

If you have ever been tested for the level of thyroid-stimulating hormone in the body, you may have a question about how often you need to donate blood for TSH to be confident in your health. Actually, it is impossible to give an unambiguous answer here, since the frequency of tests depends only on the severity of the disease and can only be determined by the attending physician.

However, in global medical practice, women over 50 years of age should have their hormone levels checked every year, because they are at risk of developing diseases associated with the thyroid gland. Also, once every six months to a year, these tests should be taken by everyone who has already been sent for this test to make sure that the TSH level has returned to normal, which means that the risk of developing diseases associated with its excess or deficiency is reduced to a negligible minimum .

TSH level norms

And now that we have learned how to donate blood for TSH to women carrying a child and everyone else, let’s figure out what the normal level of thyroid-stimulating hormone in the blood should be. Actually, this depends on several factors at once, but mainly the amount of TSH in the body depends on the age of the patient.

  1. In newborns up to 30 days, the TSH level is 0.6-10 units per liter of blood.
  2. In children aged 2 months to 2 years, TSH levels are 4-7 units per liter of blood.
  3. In children aged 2-5 years, the TSH level is 4-6 units per liter of blood.
  4. In children over 14 years of age and adults, the TSH level is 0.4-4.2 units per liter of blood.
  5. In pregnant women, the optimal TSH level is 0.2-3.5 units per liter of blood.

- what does it mean

If a blood test for TSH shows that its level in the blood is significantly higher than normal, this indicates that the patient has one of the serious diseases:

  • somatic or mental illness;
  • the development of any types of tumors, especially often pituitary tumors;
  • syndrome of lack of regulation of the body's production of TSH;
  • deterioration in the functioning of the adrenal glands;
  • pituitary adenoma;
  • late toxicosis in pregnant women;
  • primary or secondary hypothyroidism;
  • lead poisoning;
  • overdose of drugs such as Prednisolone, iodides, antipsychotics or beta-blockers, which should be stopped immediately.

Reduced levels of the hormone TSH

If the interpretation of a blood test for TSH hormones showed that the patient has a deficiency of thyroid-stimulating hormone, then this may indicate that he has no less serious diseases than with its elevated level:

  • Plummer's disease (toxic thyroid adenoma);
  • problems with the pituitary gland;
  • toxic goiter;
  • injury to the pituitary gland;
  • Sheehan syndrome, which is observed in women who have given birth and signals the death of pituitary cells;
  • hyperthyroidism in pregnant women;
  • cachexia, that is, complete exhaustion of the body;
  • diets and fasting that need to be stopped urgently;
  • excess quantity thyroid hormones, which is caused by self-medication with hormonal drugs and which should be stopped immediately.

Treatment of a patient with elevated TSH levels

And now you find out that your thyroid-stimulating hormone is elevated. What this means, your doctor will tell you in detail, who will then prescribe the appropriate treatment. First of all, he will check whether the patient is taking hormonal medications and, if necessary, prohibit their use. Instead, at the beginning of treatment, the patient will be prescribed a small amount of Thyroxine. Then from time to time you will need to check the level of TSH in the blood, and if it does not normalize, then the dose of the medicine will need to be constantly increased until the amount of thyroid-stimulating hormone is normalized.

In addition to Thyroxine, the doctor may prescribe another drug for these purposes, based on the amount of its own thyroxine that is present in the body. Also, if the level of TSH in the body is elevated, the doctor may prescribe the patient additional analysis to the level of T4 in the body, in order to use it to exclude diseases such as nodular goiter and Graves' disease. If the tests show that the patient does have Graves' disease, he will be immediately prescribed B-blockers, and in the case of nodular goiter, radioiodine therapy or surgery may be prescribed.

Treatment of a patient with low TSH levels

And finally, after we have learned how to donate blood for TSH and what its deficiency in the body means, let’s figure out how such patients will be treated. Actually, the most efficient algorithm has not yet been clearly developed here. effective treatment similar pathology. There are several methods for increasing the level of thyroid-stimulating hormone in the body, however, most often this is first done full examination patient, and the disease that provokes a decrease in TSH levels is identified, and after that rational treatment is selected for each specific case. Therefore, even if you know what the TSH hormone is responsible for, treatment should be prescribed exclusively by a highly qualified doctor; self-medication in such cases is categorically unacceptable and can only lead to an even further aggravation of the situation.

Diagnosis by an endocrinologist begins with a consideration of symptoms based on the patient’s complaints. The doctor then palpates the front of the neck, where the thyroid gland is located, checking its size. If there is a suspicion of diseases of the endocrine system, the doctor prescribes blood tests for hormones. The first priority will be a TSH test; there are several nuances in how to take it correctly.

What is TSH

This is a thyroid-stimulating hormone produced by the pituitary gland to stimulate the thyroid gland to secrete thyroid hormones, the lack or excess of which leads to symptoms. The level of TSH in the blood is directly related to the amount of these hormones, which is why it is determined first. A deviation from the norm in any direction will indicate a problem with the thyroid gland and will provide grounds for continuing the examination.

Where to begin

Choosing a laboratory is the first step you need to take. It is best to give preference to the one located at the endocrinology center. If there is none, the criterion for selection will be the method laboratory research. At the moment, there are two of them: the second (ELISA) and third (ICL) generations. The difference is in the sensitivity of the reagents and the magnitude of the error. ICL is more sensitive, but also costs more. It would be a good idea to consult with your doctor which method is best to choose; perhaps in this particular case, a cheaper one will do.

If you take it in laboratories that use computerized patient records, then you are more likely to avoid errors associated with confusion of test tubes. A barcode is applied to it and the results are automatically processed. The form is issued in print, with all the parameters, which, by the way, you can ask to be sent by email.

Myths about the rules


What affects TSH levels

Stress has the strongest effect on TSH levels. In this state, the body begins to work in “enhanced mode”, the consumption of thyroid hormones increases, and accordingly the secretion of thyroid-stimulating hormones increases. The endocrinologist’s suspicion of a pathology, which became the reason for ordering tests, is not yet a reason to panic. A calm, philosophical approach to the current situation will allow for a correct diagnosis.

When a person is cold, maintaining body temperature becomes the body's primary task. Producing heat also requires more thyroid hormone. In winter, it is necessary to avoid long walks on the eve of the test and avoid hypothermia on the way to the laboratory.

At an appointment with an endocrinologist, after ordering tests, you need to inform him about all the medications you are taking. medicines. He will adjust the appointment plan or advise cancellation. Some non-hormonal medications affect TSH levels, and to obtain correct result you will need to interrupt the reception.

What do the results mean?

Of course, only a doctor can correctly interpret the analysis, but curiosity is inherent in people, especially when it comes to health. The norm depends on age, and in pregnant women it decreases slightly, especially in the first trimester.

Low TSH

Indicates thyrotoxicosis. This means that there are a lot of thyroid hormones and the pituitary gland has stopped producing its own. This disease is accompanied by a number of symptoms: disruption of the cardiovascular system, hand tremors (on initial stage episodic), frequent mood swings (extremes - from apathy to severe anger), irregular periods, increased appetite (but no weight gain).

Elevated TSH
