Description
FT3 (Thyroid Test) Both free T3 and total T3 testing are used to evaluate thyroid function. Along with other thyroid function tests, free and total T3 tests play a role in diagnosing thyroid disorders, such as an overactive or underactive thyroid gland, assessing the severity of thyroid problems, diagnosing pituitary gland disorders, and monitoring patients with known thyroid conditions.
