When ready, your results will be delivered in a clear, easy-to-understand report. If any results suggest a potential infection, you’ll receive a call from an independent healthcare coordinator. Independent physicians are also available to answer any questions or discuss your results in detail.

Test Details & What It Measures
A Total T3 test measures the total amount of triiodothyronine (T3) in your blood, including both the bound and unbound forms of the hormone. T3 is one of the thyroid hormones that help regulate metabolism, energy, and body temperature. While Free T3 measures only the active form of T3 that is available for use by your body’s cells, the Total T3 test includes both active and inactive T3, giving a broader view of the hormone’s overall level in the bloodstream. This test can be useful for diagnosing thyroid disorders, particularly in people showing signs of hyperthyroidism (overactive thyroid), such as weight loss, rapid heartbeat, or anxiety.
Normal Total T3 levels typically range from 80 to 180 ng/dL, though these ranges can vary slightly depending on the laboratory. Low levels of Total T3 may suggest hypothyroidism (underactive thyroid), while high levels can indicate hyperthyroidism. The Total T3 test is often ordered alongside other thyroid tests, like Free T4 and TSH, to provide a more comprehensive evaluation of thyroid function and guide treatment decisions.
