[QUOTE="VA-Hiker, post: 272388, member: 46287"] I received the Quest Diagnostics dialysis Free Testosterone back, along with total testosterone, shbg, and ultrasensitive estradiol. The free testosterone is higher on this when using the same units as Labcorp. Can someone shed light on the interpretation of these results? When I use the online calculators I come up with a free testosterone of 7.34 ng/dL or 73.4 pg/mL (based on the new labs), on the labs from November I would have a free testosterone of 9.18 ng/dL or 91.8 pg/mL. It appears both Quest and Labcorp report the results in pg/mL, so they should be comparable, however even the reference ranges are widely different and so are my results. It is almost like what Labcorp reported in pg/mL is similar to the calculated values in ng/dL. Converting the Labcorp result of 6.0 pg/mL to ng/dL yields 0.6 ng/dL. Converting my new result from pg/mL to ng/dL 66.2 (pg/mL)-->6.62 (ng/dL). Thanks again, and I'm probably looking at something wrong. What is the more preferable value for looking at these numbers?
