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.
