[QUOTE="thalim90, post: 245389, member: 44997"] Hi I will update with numbers when home as I’m on mobile but I did two different tests from quest on the same blood draw. One was free t equilibrium dialysis (showed right near top of the range) while the other was free t and bioavailable t combined in one test as lc/ms/ms (showed both at very low end of the range) Why such a massive difference in results? Which do I rely on? Am I high testosterone or low? So confused. I ordered a saliva home test from myLABbox.com to try n sort this out and a test from labcorp on equilibrium ultrafiltration free t. Edit 2/7/23: All Results from Quest Diagnostics: 05/12/2017 Results: Testosterone, Free (Equilibrium Dialysis, Quest) - 151.9 pg/mL Reference Range - 35.0-155.0 pg/mL Testosterone, Total (LC/MS/MS) - 896 ng/dL Reference Range - 250-1100 ng/dL 01/26/23 Results: Testosterone, Free (Equilibrium Dialysis, Quest) - 144.1 pg/mL Reference Range - 35.0-155.0 pg/mL Testosterone, Total (LC/MS/MS) - 700 ng/dL Reference Range - 250-1100 ng/dL 01/26/23 Results: Testosterone, Free, Bioavailable and Total (MS - all below results MS) Testosterone Free 76.7 Reference Range - 46-224 pg/mL Testosterone Bioavailable 161.1 Reference Range - 110-575 pg/mL Testosterone Total: 670 Reference Range - 250-1100 ng/dL SHBG doesn't change much on all labs 39-42 Reference range 10-50 nmol/L Estradiol, Free 1/26/23 Result: 0.47 pg/mL Reference range <or= to 0.45 pg/mL Albumin 4.6-4.7 Reference range 3.6-5.1 g/dL [/QUOTE]
