[QUOTE="Simon7, post: 132378, member: 14795"] Gman, it's indeed strange that they don't specify the method of testing in the Free E2 results, contrary to the other test results. Looking in the Quest list of tests the only Free Estradiol that I was able to find is test 36169 which is using the sensitive LC/MS measurement. Perhaps the reason that the spreadsheet Free E2 calculated results correlate better when using the non sensitive E2 measurement is that the researcher who created the spreadsheet ten years ago designed the mathematical model implemented in the spreadsheet using non sensitive ECLIA test data that was probably the prevalent method at that time.
