Call me crazy, but your UNITS for the free testosterone ranges seem to be WAY off.

You say

Reference Intervals for Free Testosterone from LabCorp

* 20-29 years 9.3-26.5 picogram/mL
* 30-39 years 8.7-25.1 picogram/mL
* 40-49 years 6.8-21.5 picogram/mL
* 50-59 years 7.2-24.0 picogram/mL
* 60+ years 6.6-18.1 picogram/mL

And then say

the reference values for measuring free testosterone from Quest Diagnostics follow.

Adult Male (20-60+ years): 1.0-2.7% 50-210 pg/mL

Optimal Range: 150-210 pg/mL for aging men without prostate cancer.



Since both the ranges are in pg/mL, how can the reference values from two different labs be completely different?
