Lab ranges
15 entries
17-hydroxyprogesterone — lab reference
Female follicular <80; luteal <285; postmeno <51. Morning timing and stimulation testing may be needed.
Androstenedione — lab reference
Assay-specific and age-dependent.
DHEA-S — lab reference
M 18-30: 105-728; F 18-30: 83-377. Values decline substantially with age.
Dihydrotestosterone (DHT) — lab reference
Methods and units vary. Ask why DHT was measured and whether a target is relevant to your health question.
Estradiol — lab reference
Female cycle-phase detail is on the next section. LC-MS/MS is preferred at low concentrations.
Estrone — lab reference
Assay-specific, especially at low concentrations.
Follicle-stimulating hormone (FSH) — lab reference
Ask your clinician to read this result with age, ovarian status, testosterone/estradiol, and pituitary context.
Luteinizing hormone (LH) — lab reference
Ask your clinician to read this result with testosterone or estradiol, FSH, cycle phase, and pituitary context.
Pregnenolone — lab reference
No broadly accepted wellness target. Ask your clinician to use exact assay and clinical indication.
Progesterone — lab reference
Female phase detail is on the next section. Exogenous progesterone route/timing matters.
Prolactin — lab reference
Stress, sleep, nipple stimulation, medications, pregnancy, and macroprolactin matter.
Sex hormone-binding globulin (SHBG) — lab reference
Estrogen, thyroid, liver disease, insulin resistance, age, and medications affect SHBG.
Testosterone, bioavailable — lab reference
Depends on total testosterone, SHBG, albumin, calculation, and assay.
Testosterone, free — lab reference
Mayo example age 20-24: M 5.25-20.7; F <0.13-1.08. Declines with age and is method-dependent.
Testosterone, total — lab reference
Morning collection preferred for men. Method and age matter; confirm unexpected low values.
