Guest guest Posted May 17, 2010 Report Share Posted May 17, 2010 Hey there, I finally got my rT3 and fT3 labs in... Check out he two rT3s - done within a few weeks of each other. Do they normally vary so widely so quickly? 7 May 10 rT3 49 H (11 - 32)ng/dL FT3 5.0 H (2.0 - 4.4)pg/mL T3 125 (70 - 190)ng/dL fT4 0.74 (.59 - 1.17)ng/dL TSH <0.01 (0.34 - 4.82)uIL/mL 26 April 10 rT3 32 (11 - 32) (my fT3 tube was ruined, so needed to re-run test) Ferritin 90 (3 - 105) (as it can be a problem for folks) Any input would be great. I have lots more labs for thyroid, as well. Also, please tell me how I do the rT3/fT3 ratio. This particlar combo is not on the instruction page. I can't seeem to make the formula make sense, unless there is some multiplied factor involved. Thanks loads, jacqueline Quote Link to comment Share on other sites More sharing options...
