The 8 tests in this panel

What each one measures and the range labs usually print for adults. Ranges differ a little between labs, so the range on your own report is the one your result is judged against.

  • TSH (Thyroid Stimulating Hormone)

    A hormone from the pituitary gland that tells your thyroid how much hormone to make. It is the test most often ordered first to check your thyroid.

    11+
    0.45–4.5 mIU/L

  • Free T4 (Free Thyroxine)

    The unattached, ready-to-use part of thyroxine (T4), the main hormone your thyroid makes. It shows how much thyroid hormone is available to your body.

    20+
    0.82–1.77 ng/dL

  • Free T3 (Free Triiodothyronine)

    The unattached, active form of the thyroid hormone T3, which drives how fast your cells use energy. It is usually checked after TSH and free T4.

    20+
    2–4.4 pg/mL

  • Total T4 (Thyroxine)

    Measures all the thyroid hormone thyroxine in your blood, both the part attached to carrier proteins and the small free part.

    20+
    4.5–12 µg/dL

  • Total T3 (Triiodothyronine)

    Measures all the T3 in your blood, the more active thyroid hormone, including the part attached to carrier proteins.

    11+
    71–180 ng/dL

  • Reverse T3

    An inactive by-product of thyroxine (T4). Its usefulness is limited, and an American Thyroid Association review says routine testing is not needed.

    Adults
    8–25 ng/dL

  • Thyroid Peroxidase Antibodies (TPO)

    Antibodies aimed at an enzyme in the thyroid. They are linked to autoimmune thyroid conditions such as Hashimoto's thyroiditis.

    20+
    0–34 IU/mL

  • Thyroglobulin Antibodies

    Antibodies aimed at thyroglobulin, a protein made in the thyroid. They are linked to autoimmune thyroid conditions and affect thyroglobulin testing.

    Adults
    0–4 IU/mL
