[QUOTE="nicknot, post: 201005, member: 41132"] I'm having some trouble understanding how different ranges relate to each other. For example, the non-Dialysis Free T mehod at Quest has a range of 46-224pg/mL for 18-69yo males ([URL='https://testdirectory.questdiagnostics.com/test/test-detail/18944/testosterone-free?cc=MASTER']Quest Diagnostics: Test Directory[/URL]). However the Dialysis Free T range shows 35-155pg/mL on my lab report. My results came back at 240pg/mL on the 35-155 range. Does that mean they would've come back at around 350pg/mL on the 46-224 range? If my results would've come back the same (240pg/mL) on the 46-224 range, it would mean that one of their Free T tests says I'm at the top of the normal range, and their other test says I'm completely superhuman. In other words, both tests for the same marker would place me at completely different percentiles relative to the population, which makes no sense. EDIT: Same thing with Labcorp for ex. Their range is 9-26ng/dL. Would I test also at 24ng/dL (equivalent to my 240pg/mL with Quest)? Or a (proportional to my Quest result) ~35ng/dL? If it's the former, again it would mean both labs place me at completely different percentiles. How does this make any sense? [/QUOTE]
