To diagnose a number of diseases are sometimes required to be tested for blood levels of thyroid-stimulating hormone . The deviation from the standard indicators of TSH usually indicates a problem in the body, although any case and considered individually. So the doctor will refer you to the analysis . How should I prepare for it , what to expect from this study ? Here the necessary information .
The gland of the brain, the pituitary gland synthesizesthyroid-stimulating hormone- Control of the thyroid gland . It stimulates the thyroid gland T3 ( triiodothyronine ) and T4 ( thyroxine ) . Once the levels of these hormones grows , they , in turn , begin to suppress the release of TSH. This self-regulating system can falter , and then the hormone imbalance adversely affect the function of many organs . It is no wonder that the appointment of content analysis TTG you can get not only on the endocrinologist , but also from the therapist , gynecologist , neurologist , surgeon.
Women over the age of forty years, is especially important to determine the level of thyroid stimulating hormone . Not less important it is for women who want to get pregnant - otherwise the pregnancy may not occur or may be harmful to an unborn baby .

Blood analysis on TTG is taken from a vein in the morning: at this time, the concentration of the hormone is highest.
Are you interested in so as not to distort the result of the analysis - so you need to know some rules.
- For a day or two before the analysis can not be physically and emotionally overstrained.
- In the morning, on the eve of the analysis should not have breakfast (we can only drink plain still water).
- If you are already taking thyroid hormone or steroid medications 48 hours prior to receiving the analysis it must be stopped , but only by following the advice of a doctor . The same applies to some drugs that increase the level of TSH (eg, furosemide, motilium , prednisolone ) .
Average content of interest to us is not the same hormone in both men and women , so you need to specify the rate of an endocrinologist in each individual case . By the way, your total deviation from the norm - not always evidence of the disease. TSH level is usually increased during certain periods of pregnancy , often - after exercise , when taking certain medications , etc.
With regard to the interpretation of the results of analysis in the case where the content of the hormone is not correct - trust your doctor.
