A healthy result should fall into the range 2.3 - 14 ng/mg.

Epi-Testosterone is one of several naturally-occurring testosterone compounds in the body that act as steroids. In the average male, four times as much testosterone is produced as Epi-Testosterone. 

The Epi-Testosterone test is usually ordered to see if an athlete (or police officer sometimes) has been taking non-prescription testosterone in any way, shape or form. Then the levels of Epi-Testosterone are compared to the levels of testosterone. The reasoning here is that if testosterone is being taken, then Epi-Testosterone levels will not show an appropriate increase.

Normal Ranges for Epitestosterone in ng/mL:

Men: 4 times as much testosterone as Epi-Testosterone, or less (Studies show ratios in athletes from 1/1 to 1.5/1 although there may be ethnic variation.)

Ratio >4 parts testosterone: 1 part Epi-Testosterone means there may be possible doping. (The original guidelines were a ratio of 6:1 in 1982.)

Critical Range: Epi-Testosterone urine levels >200 ng/mL is definitive and means there is some doping occurring.)
