TTG - transcript. The analysis of a blood, TTG - decoding
Some people meet with the fact that theyprescribe an analysis on TTG, the decoding of which is unknown to them. It is a thyroid-stimulating hormone, which is the glycoprotein hormone of the pituitary gland. Among them also can be named hCG, FSH and LH. But it is the thyroid-stimulating hormone that is the main regulator of the functioning of the thyroid gland. The index of its secretion controls the thyrotropin-releasing factor. It also regulates the secretion of thyroxin and triiodothyronine, which have the designations T4 and T3, respectively. Their concentration is very important in human blood, and its fluctuations are proof that serious changes are taking place in the human body.
The importance of thyroid-stimulating hormone in the human body 
The interpretation of TSH analysis plays an important role forall people. This hormone seriously affects the various metabolic processes that occur in the thyroid gland. They have a connection with the receptors of the cell membrane, which activates the adenylate cyclase. The latter provokes the development of the AMF. As a result, synthesis and secretion of T3 and T4 are enhanced, and the thyroid remains physically integral and its functions are not disturbed. The concentration of the hormone allows you to determine the blood test of TSH, the transcript of which will draw a clear picture of what is happening. As a rule, he is appointed in such cases:
- to exclude hyperthyroidism or hypothyroidism;
- to trace the result of antithyroid therapy during hyperthyroidism;
- to monitor the suppression of T4 in a nontoxic goiter, or to control the suppression of T4 - the trophic effect of TSH in nontoxic goiter or "cold nodes";
- in order to evaluate the response to the stimulating test.
Indications for conduction
- for screening examination of TSH analysis, the decoding of which will enable to determine the latent hypothyroidism;
- for differential diagnosis of diseases associated with the thyroid gland;
- to determine the stage of primary hypothyroidism or hyperthyroidism;
- to monitor the adequacy of treatment with hormones.
Preparation for analysis
In order for the study to be correct,blood should be taken on an empty stomach. Only water is allowed. Must pass at least 8 hours after the last meal. The examination should be performed before the medication has started. If they have already been taken, then it is necessary to wait, when two weeks have elapsed since their last use. If you need to be examined during medication, then you should definitely indicate what the patient is taking. Before the examination for the day you can not eat fried and fatty foods, alcohol is prohibited and serious physical strain. Do not go to the laboratory after physiotherapy, rectal examination, ultrasound, fluorography, x-ray. The result of the study may affect individual medications, such as acetylsalicylic acid, corticosteroids, iodine preparations. Hilosis samples and hemolysis are also one of the factors that can affect this kind of examination.
Interpretation of results
A blood test on TTG, the transcript of whichgives an excellent opportunity to evaluate the functioning of the thyroid gland, is very important for those people who have certain health problems. Investigating the patient, the clinician pays special attention to the lower value of this indicator. The concentration of this hormone is very important in such cases:
- when it is necessary to diagnose thyrotoxicosis;
- in order to follow the various forms of goiter;
- in order to suppress the level of TSH and differentiate the true thyrotoxicosis that occurs during the bearing of the child;
- to find out the reasons for the differences in the results of the determination of T4 and the thyroid-stimulating hormone itself with the clinical picture;
- in case of consumption of a large number of hormones thyroid;
- in case of taking medications that contain T3;
- if there is a vnetreoidal pathology;
- In case of insufficient therapy with hormones thyroid;
- when using drugs that can affect the thyroid status;
- in case of total resistance to thyroid hormones.
There are certain indicators, according towhich determines the blood test TSH, decoding, the norm. In accordance with them in men this result reaches the highest value of 3.5 in 10 years, and in women it reaches 4.2. The highest result can be observed in pregnant women in the last trimester - 3.2.
What is the result of high results?
When tests for hormones TTG are handed over, their interpretation shows that the indicator exceeds the norm, this indicates the possible presence of such diseases as:
- thyroid cancer;
- endemic goiter;
- ectopic secretion, which occurs with tumors of the lung or breast;
hypothyroidism of the thyroid gland at the initial stage;
- Pituitary tumor.
What is the low indicator?
If the results of the analysis are below the norm, this also indicates various pathologies, among which:
- trauma or swelling of the pituitary gland;
- the presence of Isenko-Cushing syndrome;
hypothalamic-pituitary insufficiency;
- Hyperfunction of the thyroid gland in the primary stage.
Thus, we see that the analysis of TSH,deciphering it is very important for every person. This hormone regulates all the work of the thyroid gland, and in it there are quite serious metabolic processes that seriously affect the human condition. Any deviation from its norms can lead to serious consequences. Often even a lethal outcome is possible. That's why you should be careful enough about your health. If the state of health worsens, do not hesitate, we must go to the doctor. The specialist will appoint appropriate tests and be able to warn the disease in time or its dangerous consequences. Take care of yourself, your loved ones and be healthy!
