[QUOTE="tareload, post: 242091"] Hmmm, I've never seen an LCMS assay with lower reference range that high. For example, Quest: [URL unfurl="true"]https://testdirectory.questdiagnostics.com/test/test-detail/30289/estradiol-ultrasensitive-lcms?cc=MASTER[/URL] [ATTACH type="full" alt="1672842214167.png"]28250[/ATTACH] ARUP: [URL unfurl="true"]https://ltd.aruplab.com/Tests/Pub/0093247[/URL] [ATTACH type="full" alt="1672842282091.png"]28251[/ATTACH] Very consistent male reference ranges among the US [I]reference[/I] laboratories. Quest always appears the odd duck and as [USER=13851]@madman[/USER] has noted multiple times they still aren't part of [URL='https://www.cdc.gov/labstandards/pdf/hs/CDC_Certified_Estradiol_Procedures-508.pdf']Host standardization list[/URL].
