Thyroxine Binding Globulin Blood Test

Virginia rates for HCPCS 84442

A blood test that measures the level of thyroxine binding globulin, a protein made by the liver that carries thyroid hormone through the bloodstream. It helps doctors interpret thyroid hormone levels correctly, since changes in this carrier protein — from pregnancy, liver disease, certain medications, or inherited conditions — can make total thyroid hormone results look abnormal even when thyroid function itself is normal. A small blood sample is all that's needed.
