Common Thyroid

What is the Thyroid?

The thyroid is a small, butterfly-shaped gland located at the base of the neck. It serves as an endocrine and produces hormones which help regulate various body functions, including temperature, metabolism, and energy. When the thyroid is functioning normally, it produces the ideal amount of hormones needed for the body to function correctly. However, when the thyroid does not produce enough or too much hormones, it can lead to various health issues.

There are several thyroid tests used to diagnose and monitor thyroid conditions. The most common tests include thyroglobulin, thyroid-stimulating hormone (TSH), and free thyroxine (T4).

Thyroglobulin Test (Tg):

The thyroglobulin test measures the amount of thyroglobulin in the blood. This test is used to detect thyroid cancer, and monitor the efficiency of treatment.

Thyroid-Stimulating Hormone Test (TSH):

The thyroid-stimulating hormone test measures the level of TSH in the blood. Low levels of TSH are associated with hyperthyroidism, while high levels of TSH commonly indicate hypothyroidism.

What to Expect During Thyroid Testing
