Guest guest Posted November 21, 2008 Report Share Posted November 21, 2008 I had some blood done with everything coming back normal and the following T3 and RT3 results Triiodothyronine, Free, Serum, -3.1--normal range (2.3 - 4.2 pg / mL) Reverse T3--323-normal range (90 - 350 pg / mL) I posted this on Realthyroidhelp.com and person recommended this board and also explained that my RT3 are high and when you take you T3 over you RT3 the ratio should be .02 or higher mine is .0096. Possible reasons I was told for this is high cortisol level and / or low B12. I just got back results from another blood test and the results are B12 -1124 pg/mL - normal range 211-946 ( I was actually higher then normal range not lower) Cortisol (am blood) - 12.0 ug/dL -- normal level for AM is between 6-30 ug / dl the only other thing that came back out of range was my Iron was low 55 ug / fl ----- normal range is 61-157. Could that have something to do with this. I am really confused. Quote Link to comment Share on other sites More sharing options...
