These ranges are illustrative and compiled from standard laboratory references. Real reference ranges vary meaningfully between labs and assays — always interpret your results against the range printed on your own lab report, with your clinician. Female testosterone ranges in particular differ widely between methods. This tool does not diagnose anything and is not a substitute for medical care.

Why a single hormone level rarely settles the question

For women going through menopause at the typical age, the diagnosis is usually clinical — based on symptoms and menstrual pattern — and routine hormone testing often isn't needed.1 During perimenopause especially, estrogen and FSH can swing dramatically from week to week, so a single blood draw can be misleading; what looks "postmenopausal" one day may look "premenopausal" the next.

Treatment is generally guided by how you feel, not by chasing a target number. The major exception is testosterone: if it's used for low sexual desire, the consensus is to keep blood levels within the normal premenopausal female range to avoid side effects — one of the few places a number genuinely guides dosing.2 And as the wide, lab-dependent ranges above show, there is no agreed "optimal" female testosterone level to aim for.3
