100–200 pg/mL <55 ng/dL [4] Callen-Lorde: United States "Some guidelines recommend checking estradiol and testosterone levels at baseline and throughout the monitoring of estrogen therapy. We have not found a clinical use for routine hormone levels that justifies the expense.
The free androgen index is intended to give a guide to the free testosterone level, but it is not very accurate (especially in males — see endocrine society commentary below). Consequently, there are no universally agreed 'normal ranges', and levels slightly above or below quoted laboratory reference ranges may not be clinically significant.

With immunoassay-based techniques, testosterone levels in premenopausal women have been found to be about 40 ng/dL (1.4 nmol/L) and DHT levels about 10 ng/dL (0.34 nmol/L). [5] [74] With radioimmunoassays, the ranges for testosterone and DHT levels in women have been found to be 20 to 70 ng/dL and 5 to 30 ng/dL, respectively. [74]
Normal total testosterone levels depend on the man's age but generally range from 240 to 950 ng/dL (nanograms per deciliter) or 8.3–32.9 nmol/L (nanomoles per liter). [11] According to American Urological Association, the diagnosis of low testosterone can be supported when the total testosterone level is below 300 ng/dl. [ 12 ]

[6] 99% of the female athletes at those competitions had testosterone levels below 3.08 nmol/L. [6] However, a study of endocrine profiles in 693 elite female and male athletes published in 2014 found that only 13.7% of the elite female athletes had high levels of testosterone while as many as 16.5% of the elite male athletes had low levels of ...
