Name the thyroid function test with the normal range

Thyroid function tests (TFTs) are a series of blood tests that measure various aspects of thyroid gland function. These tests are crucial for assessing thyroid health and diagnosing conditions such as hypothyroidism and hyperthyroidism. Here are common thyroid function tests along with their normal reference ranges:

1.     Thyroid-stimulating hormone (TSH): 0.4 to 4.0 mIU/L

2.     Free Thyroxine (FT4 or Free T4): 0.8 to 1.8 ng/dL or 10 to 23 pmol/L.

3.     Total Thyroxine (TT4 or Total T4): 4.5 to 12.5 µg/dL or 58 to 161 nmol/L.

4.     Free Triiodothyronine (FT3 or Free T3): 2.3 to 4.2 pg/mL or 3.5 to 6.5 pmol/L.

5.     Total Triiodothyronine (TT3 or Total T3): 80 to 200 ng/dL or 1.2 to 3.1 nmol/L.

6.     Thyroglobulin (Tg): less than 55 µg/L.

7.     Thyroid Peroxidase Antibodies (TPOAb): Less than 9 IU/mL

8.     Thyroglobulin Antibodies (TgAb): Less than 4 IU/mL
