When a doctor suspects that you may have a thyroid disorder, гормоны щитовидной железы one of the first tests they will order is a thyroid function test (TFT). These tests measure the levels of hormones produced by the thyroid gland, which are crucial for regulating metabolism. Understanding what these tests mean can be daunting, but it's essential to make informed decisions about your wellness. In this article, we will break down the common thyroid function tests and what they indicate.

Thyroid-Stimulating Hormone (TSH) Test
--------------------------------

The TSH test is the first test your doctor will order when evaluating thyroid function. TSH is a hormone produced by the pituitary gland that regulates the production of Th3 and Th4. The TSH test measures the levels of TSH in your blood. If your TSH levels are:

• High (above 5 mIU/L), it means your thyroid gland is not producing enough thyroid hormones, a condition known as hypothyroidism|thyroid insufficiency|low thyroid function}.
  
• Low (below 0.5 mIU/L), it means your thyroid gland is overactive and producing too many thyroid hormones, a condition known as hyperthyroidism|thyroid excess|high thyroid function}.
  
• Normal (0.5-5 mIU/L), it indicates that your thyroid gland is functioning normally.
  
  

Total Thyroxine (T4) Test

------------------------

The T4 test measures the levels of Th4 protein in your blood. Th4 is a hormone produced by the thyroid gland that is converted into triiodothyronine (T3) in the body, which regulates overall health. If your T4 levels are:

• Low, it indicates hypothyroidism.
  
• High, it indicates hyperthyroidism.
  
  

Free Thyroxine (FT4) Test

Free Triiodothyronine (FT3) Test
----------------------------------

The FT3 test measures the levels of free Th3 hormone in your blood. FT3 is the active form of thyroid hormone that regulates metabolism. If your FT3 levels are:

• Low, it indicates hypothyroidism.
  
• High, it indicates thyroid excess.

Thyroglobulin Antibody Test
---------------------------

Interpreting Thyroid Function Tests
--------------------------------

• The levels of TSH, T4, FT4, T3, and FT3
  
• The presence of thyroid proteins
  
• Your medical history
  
• Your symptoms
