  • 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

  • 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

  • T3 Uptake

    Shows how many binding spots on your blood proteins are open for thyroid hormone. It is not a hormone level, and it is used to work out the free thyroxine index.

    Adults
    22–35 %

  • Free Thyroxine Index (T7)

    A calculated estimate of how much active thyroxine (T4) is available, worked out from total T4 and T3 uptake. It is an older alternative to measuring free T4.

    Adults
    1.4–3.8 index
