Guest guest Posted January 11, 2010 Report Share Posted January 11, 2010 Hi all, I am 6 weeks into T3 only with SRT3. Overall, feeling better and temps slowly improving. Got my new labs today, but they didn't give Free T3, only T3 Uptake. I know there is a different ratio if you don't have FT3 reading to calculate a ratio where it needs to be above 10. Is that using the T3 Uptake? Could someone give me some help with this? My labs 6 weeks ago were: FT3: 325 (230-420) pg/dL T3 Uptake: 32..5 (27.8-40.7) RT3: 32 (11-32) ng/dL FT3/RT3 ratio: 10.15 indicating reverse t3 problem because not above 20. My latest labs are: T3 Uptake: 28.5 (27.8 - 40.7) RT3: 19 (11-32) ng/dL Is this a ratio of T3/RT3 of 1..5? Looks like RT3 has improved, but ratio (if I did it correctly using T3 Uptake) needs to be above 10 to resolve RT3 dominance. Is that right? Any help is appreciated. Thanks, Beth S.
