Thyroid Disorders
Total T4 levels offer a good index of thyroid function when TBG is normal and non-thyroidal illness is not present.
What is this test?
This assay is useful for monitoring treatment with synthetic hormones (synthetic T3 will cause low total T4). It also helps to monitor treatment of Hyperthyroidism with Thiouracil or other anti-thyroid drugs.
Total T4 (Thyroxine) is offered as a lab test. Follow preparation instructions if any, and consult your doctor to interpret results.
