Abstract
It is well known that I'll-triiodothyronine resin sponge uptake test (Triosorb test) is a very useful and easy procedure for the determination of thyroid activity. However, this method has an inevitable problem of fluctuating standard values (resin sponge uptake % of standard serum) of each kit, which makes universal comparison of Triosorb values obtained on patients impossible. The method presented here utilizes 30% correction on the standard value of each kit and provides a solution on the problem due to the fluctuating standard values. Therefore, universal comparison of Triosorb values obtained by different kits having different standard values becomes possible.
