Description

A Thyroxine Free Blood Test measures the amount of T4 in relation to the amount of thyroxine-binding globulin present. Free T4 is a small part of total T4. Increased free T4 levels may occur in people without thyroid diseases. The free thyroxine value can indicate when an abnormal level of T4 is due to an abnormal level of thyroxin-binding globulin in the blood. Generally, free thyroxine is run with other thyroid tests so that it is meaningful (see Thyroid Panel with TSH test).

A Thyroxine T4 Free direct blood test is used to evaluate thyroid function in individuals who may have protein abnormalities that could affect total T4 levels.
