Biomarkers Measured



A hormone produced in the brain that tells the thyroid gland to make T3 and T4. Measurement of TSH is the foundation for assessing thyroid function.


Free T3

One of the two major hormones made by the thyroid gland. It regulates metabolism, body temperature, weight, energy, and heart health.


Free T4

T4 is the hormone made in the greatest quantity by the thyroid gland. It can also be converted to T3. It has the same actions as T3, but it’s not as strong.



Thyroid peroxidase antibodies (TPO Abs) are antibodies made by the immune system that suppress thyroid function.
