The Thyroid gland – this is a very important organ in the body that synthesize hormones, which are the development of bone tissue, the metabolism, the nervous system functions. It plays a significant role in the growth and development of the body. Intellectual development of man may be affected if the hormonal background is broken by disease or congenital defect. Insufficient condition of that organ at birth, when the norm of thyroid hormones, causes such diseases as cretinism and myxedema (edema over the body with severe manifestations in the skin: density, dryness, peeling).
Location, function and performance - the thyroid hormones
A Gland located at the front of the neck, is called the endocrine, the weight of 18-20 grams. It produces in conjunction with the pituitary hormone TSH regulates the synthesis of important hormones such as T3 and T4, containing atoms of iodine. Thyrocalcitonin the hormone controls the metabolism of calcium. The thyroid gland contains a large number of blood and lymphatic vessels. This is because there are no ducts, hormones are being secreted directly into the bloodstream, so the rate of thyroid hormones are very important for stable operation of numerous systems of the human body.
The Surface of the rear layer contains the thyroid gland the parathyroid glands responsible for regulating calcium in the body. Little dots on the gland size of 6 mm by 4 mm and 2 mm thickness so important that their removal can lead to death.

During the inspection, you may experience dryness of the skin, pain when swallowing saliva and food, increased sleepiness. Then the man passes the supplementary examination, laboratory tests and tests to determine normal thyroid hormones (TSH-T3 and T4). In the case of tumor development, spend a puncture biopsy.
Despite the fact that the validity of research is high enough, should undergo ultrasound to check the blood cancer, as well as to do a cat scan to rule out the randomness of the diagnosis, as there are a considerable percentage of – up to 5% false negative results.
Analysis on hormones of a thyroid gland, Norma
Norm indicators in the research is:
1. TSH-the hormone that stimulates the production of T3 and T4 from 4 to 44 mu/L.
2. T3 – from 2.5 to 5.8 pmol/L.
3. T4 – from 9 to 21 pmol/L.
4. Antibodies (at-TG) – up 17.9 U/ml.
5. Antibodies (TPO) from 5.5 U/ml and above.
To Evaluate the results of tests can only an endocrinologist, because the values may be different (women, for example, during a menstrual cycle hormones can be increased), the human condition, the age, the methods used – all of this can change the results of laboratory tests.
