Two days ago, there was an excellent discussion/explanation of RT3 (and also, FT3), their roles, and what to look for when deciphering thyroid blood results. For the first time I felt like it had been explained in such a manner that my brain understood. I kept the discussion open so that I could apply it to my own tests when, alas, the discussion has poof! vanished. (The original poster appears to have "left the building" and took all their posts with them..sigh).
Can whomever who provided that excellent concise explanation please do so again?
