That's a loaded question. Are you asking pre HRT, or Hormone Replacement Therapy (HRT) #'s? What age?
For my age the mean # is 617, I personally think anything under 400 is low, the new scale has 350 as the lowest of range.
And the tests depend on the time of day, and I'm also assuming blood #, not saliva.
Get a blood test before 10am, they say fasting doesn't matter, but I've got first hand experience that coffee can really spike the results. I also get other things tested, so I fast for 12 hrs before hand.
What's your number?
