Effective September 29, 2014, Gamma-Dynacare Medical Laboratories will be changing the methodology for free testosterone (FT) measurement. FT results will be calculated using Vermeulen’s equation1, incorporating the levels of serum total testosterone, sex hormone binding globulin (SHBG) and albumin. The current analogbased measuring method will be discontinued. For more information, please see the Client Notice below.
