What factors could influence total T result?

Any of these would suffice but test #1 is expensive and #3 from Nelson's discountedlabs. would be the cheapest option!

Test #2 is the one I would get (cost/reference range).




1. 500726: Testosterone, Free, Mass Spectrometry/Equilibrium Dialysis (Endocrine Sciences) | Labcorp
Methodology: Testosterone: high-pressure liquid chromatography (HPLC)/tandem mass spectrometry; free testosterone: equilibrium dialysis


2. 070038: Testosterone, Free, Equilibrium Ultrafiltration With Total Testosterone, LC/MS-MS | Labcorp
Methodology: Free: equilibrium ultrafiltration; total: liquid chromatography/tandem mass spectrometry (LC/MS-MS)


3. Testosterone, Total, LC/MS and Free (Equilibrium Dialysis)

Ok great. I can't use Quest here in NJ, so I can't go with Nelson. I can do 070038 through Marek for $89. Marek says it is LC/MS instead of LC/MS-MS, but when I look it up directly on LabCorp, it is LC/MS-MS. Perfect!
