A Thyroid function (TFT) blood test

A TFT blood test, also known as a thyroid function test, is a type of test that measures the levels of hormones produced by the thyroid gland in the blood. The thyroid gland is a small gland located in the neck that plays a crucial role in regulating the body's metabolism. It produces two hormones, thyroxine (T4) and triiodothyronine (T3), which help control the body's energy production and metabolism. This test is commonly ordered when a person has symptoms that may be caused by a thyroid disorder, such as fatigue, weight gain, and hair loss. It can also be used to monitor the effectiveness of treatment for these conditions.
