How do doctors diagnose thyroid problems?
One of the most definitive ways to diagnose a thyroid problem is through blood tests. Thyroid blood tests are used to tell if your thyroid gland is functioning properly by measuring the amount of thyroid hormones in your blood. These tests are done by taking blood from a vein in your arm.

Why would a doctor order a thyroid test?

What are the 5 thyroid tests?
Blood tests for your thyroid include:
- TSH – measures thyroid-stimulating hormone. It is the most accurate measure of thyroid activity.

- Antithyroid antibody test – measures antibodies (markers in the blood).
