Hi TUKs,
We have been asked for a fair few Reverse T3s over the last couple of years or so - but without looking through all of the results and going from memory I'm unsure if anyone has ever actually had a reverse t3 that is out of range. It's an expensive test relative to all of the others, but I know that it is well celebrated in the online thyroid community generally, maybe due to the technique/method . My question is has anyone ever had a RT3 result come in out of range? And has a RT3 result one way or the other ever come in useful in obtaining treatment?
