T3 is a thyroid hormone. Hormones occur in two different states in the body-bound (to a protein) and free (not bound to protein). A free T3 test is one that measures the concentration of unbound T3 in the blood.

Why are they reluctant to do the thyroid T4 test?
The old Total T4 test (TT4) is no longer considered the best way to test for T4 levels. T4 and T3 can both be bound by other proteins and hormones in the body. When this happens, the T4 or T3 is not usable by the body. The body can only use T4 and T3 that is not bound, or free. For this reason, Free T4, which only tests the free levels of the hormone, is now preferred over Total T4 testing as more accurate.

What is the most appropriate single screening test for thyroid disease?
The test for Thyroid Stimulating Hormone (TSH) USED to be considered the gold standard test for thyroid dysfunction. This has changed. Since TSH values only reflect the average of the thyroid's activity over several weeks, doctors now know to test TSH, Free T3 and Free T4 as well as TPOabs to help screen patients for thyroid dysfunction.
Why is T3 level more reliable in testing hyperthyroidism?
Between T3 and T4, T3 is the bioavailable form of the hormone which the body is able to actively utilize to control metabolism. T4 is only storage hormone, making it a less reliable predictor of current metabolic functions since it must first be converted. Some patients are unable to convert T4 to T3 effectively. Totals are less reliable than Frees however, so between the two hormones, the most reliable hormone to test is Free T3, not Total T3. That said, diagnosing thyroid dysfunction requires multiple tests for appropriate diagnosis, since the overall impression is most important in the diagnostic process, not a single hormone.
