Further to the links I posted today on the new version of the app SPINA Thyr that gives a numerical analysis of Thyroid blood test results, I printed out my results to discuss at my next endo appointment, when I noticed that not only was the GD conversion efficiency below range but also the TSHI, sTSHI, and TTSI were marked as being out of range. I searched to find out the meaning of these numbers as they are not really covered in the manual and eventually found this webpage on interpretation of SPINA Thyr results.

This is an extremely detailed article on using and analysing the results of the App.
