Health Tip: Differing Thyroid Tests

By on August 21, 2018

The thyroid is an endocrine gland that makes hormones and helps regulate bodily activities, such as how fast you burn calories and how fast your heart beats.

Doctors may suggest a thyroid test if they suspect the gland is overactive (hyperthyroidism) or underactive (hypothyroidism).

The U.S. National Library of Medicine says potential tests may include:

  • TSH – Measures thyroid-stimulating hormone. This is considered the most accurate measure of thyroid activity.
  • T3 and T4 – Measure different thyroid hormones.
  • TSI – Measures thyroid-stimulating immunoglobulin.
  • Antithyroid antibody test – Measures antibodies (markers in the blood).
