Who is this test for?

This test is for anyone who is 18 years old and older and wants to understand their thyroid function better.

Your thyroid plays an important role in how your body functions from controlling your metabolism to regulating your heart rate. Many symptoms of thyroid dysfunction, such as fatigue, weight gain, or hair loss, can be mistaken for something else.

What does this test measure?

Thyroid-stimulating hormone (TSH), also known as thyrotropin, is a hormone that stimulates the thyroid gland to produce free thyroxine (FT4) and free triiodothyronine (FT3).
