Free T3 Blood Test

Michigan rates for HCPCS 84481

This blood test measures the amount of triiodothyronine, or T3, that is freely available in the blood to act on the body's tissues, rather than the portion bound to carrier proteins. It helps evaluate thyroid function, particularly when other thyroid tests suggest an overactive thyroid.
