From your test results your Free T4 was a bit lower than we normally suggest, which is middle of the
range, at minimum. Your Free T3 is even lower in its
range, which shows that your body is not converting T4 to T3 very well. Free T3 is the thyroid hormone that correlates best with symptoms. Many members say that symptom relief required Free T4 at the middle of its range, and Free T3 in the upper third of its range, or as necessary to relieve symptoms.
