RT3(U) or RT3U is a resin T3 uptake test. It does NOT measure RT3 but the proteins binding T3. If you measure Total T3 and subtract the bound fraction, you get the Free T3 or FT3. None of this has anything to do with Reverse T3. Chuck Quote Link to comment Share on other sites More sharing options...
