[QUOTE="tareload, post: 227998"] Would be the same as the reference range for fT by equlibrium dialysis (ED) methods assuming this calculator fits the ED data well. Oh wait, that's right we are still debating the fT by ED ref ranges and whether Vermeulen (ISSAM) or Tru-T is "right". :) [URL unfurl="true"]https://www.excelmale.com/forum/threads/public-service-announcement-piss-poor-direct-ria-ft-measurement-help-is-on-the-way.25288/[/URL] [IMG]https://www.excelmale.com/forum/attachments/1652457239528-png.21777/[/IMG] [I][B]Does anyone know the free testosterone reference range for the ISSAM calculator?[/B][/I] [USER=38109]@Cataceous[/USER] has stated probably 10-20 ng/dl is "decent" which would line up kinda decently with Labcorp normal range for fT by ED (5 to 28 ng/dl). Good post [USER=43366]@ResearchIt[/USER]. Would be fun to compare UF number from Labcorp against ED. Many times Quest and Labcorp fT by ED numbers will either agree with ISSAM (Vermeulen or cfTV) or Tru-T (cfTZ or Zakharov in above plot). I haven't seen a parity plot of Labcorp UF method vs ED for fT. I am still betting on cfTV but happy to be proven wrong. We got no idea. [/QUOTE]
