A 20-year-old male asked:

How do the free t3 (liothyronine) t4 differ from total t3 (liothyronine) t4 ? and which of them is more accurate in diagnosing thyroid issues along with the tsh test ?

Prefer the frees: Totals are cheaper but require a little interpretation. Both are accurate. Thyroid disease is often underappreciated and i'm glad you're being checked.

Doc is testing tsh, t3 (liothyronine), (liothyronine) t4, free t3 (liothyronine), (liothyronine) free t4, and reverse t3 (liothyronine). Are there other tests that should be done at the same time as these tests for thyroid?

If my tsh low, t3 (liothyronine) and t4 is normal, is it hypo or hyper thyroidism? Should I take iodine? Ultra sound is normal, without pathology.
