Guest guest Posted March 4, 2010 Report Share Posted March 4, 2010 After 1 week of starting T3 treatment, I have the following labs for Free T3 and Reverse T3: Free T3: 3.6 Reference: 2.3 - 4.2 Reverse T3: 163 Reference: 90 - 350 So, to calculate the ratio, would this be correct: (3.6 x 1000)/163 = 22.1? This, to me, is not indicating a reverse T3 issue - however, I don't have a reverse T3 lab to show prior to starting treatment, as no doc had ever tested me for it before. My Free T4 and Free T3 lab 3 weeks ago did, however, indicate a conversion issue (see labs at the bottom of this post). So, my questions are: 1) is it likely I have a RT3 issue, knowing the above labs were after just one week of T3-only treatment 2) am I still in the right place with this group and in treating with T3-only if I don't have an RT3 issue but rather have a conversion issue? These can be separate issues that still require the use of T3-only, correct? Please view my labs below. The labs below I had done 2 weeks prior to beginning T3 treatment and 3 weeks prior to the labs above. Note: I've never felt well on T4-only treatment - the labs below reflect being on no medication for 2 months. 3 weeks prior to these labs, I'd shown these: TSH - 6.2 (0.5 - 3.0) Free T4 - 1 (0.7 - 2.5) Free T3 - 2.4 (2.5 - 6.5) TPO Blood Spot - 12 (0 - 150) (70 - 150 borderline) Thoughts on the above??
