What Is a Thyroid Function Test?
A thyroid function test is a blood test used to measure how well your thyroid gland is working. The thyroid gland controls metabolism, energy levels, heart rate, body temperature, and many hormonal processes in the body.
Thyroid disorders are common and often develop gradually. Testing helps detect thyroid problems early and guides appropriate treatment.
