[QUOTE="Dr Justin Saya MD, post: 74903, member: 12687"] As FYI and discussion topic for the community, effective July 17, 2017 the LabCorp reference range for total testosterone measurement in adult males will be changing (DECREASING) to 264 - 916 ng/dL (previously 348 - 1197 ng/dL). Please note the METHODOLOGY for the assay is not changing in any way, only the reference range is changing. [url]https://www.labcorp.com/assets/11476[/url] Reasons for this change, as cited by LabCorp, include pressure from the CDC for standardization across labs of testosterone reference range and, ultimately, a different study/patient population used for the two ranges. The low end cut-off for both ranges is the bottom 2.5 percentile of the patient population. As I already KNOW what OPTIMAL testosterone levels are for most males (based upon treating over 10,000 of them), this simple change in reference range is not going to negatively impact my patients...however, I fear this change is going to lead to even MORE guys walking in to their PCP or other provider with classic hypogonadal symptoms but T levels "in range" (now all the way down to 264!) and being told they're "normal" and given an SSRI + viagra and sent out the door to continue to suffer.
