What does this converter do?

This tool converts 17-Hydroxyprogesterone values between nmol/L, ng/mL, ng/dL, ng/100mL, ng%, ng/L, µg/L, and pg/mL. The conversion is specific to 17-Hydroxyprogesterone and should not be used for progesterone, cortisol, testosterone, estradiol, or any other steroid hormone.

Conversion formulas

nmol/L = ng/mL × 3.026

ng/mL = nmol/L × 0.3305

nmol/L = ng/dL × 0.03026

ng/dL = nmol/L × 33.05

ng/100mL = ng/dL

ng% = ng/dL

µg/L = ng/mL

pg/mL = ng/L

Example conversion

If 17-Hydroxyprogesterone = 10 nmol/L, then 17-OHP ≈ 3.30 ng/mL, ≈ 330 ng/dL, and ≈ 3305 ng/L.

Important laboratory note

17-Hydroxyprogesterone reference ranges vary by age, sex, menstrual or gestational status, sampling time, assay platform, and laboratory method. This converter only changes units and does not diagnose congenital adrenal hyperplasia, adrenal disease, or any other endocrine condition.
