I've done a bit of research and I find the range
you gave above (7.7-58.5), often used in relation to Luteinizing Hormone
(LH), which is a hormone released by the pituitary. LH rises about mid cycle when ovulation occurs. It is used when women have difficulty getting pregnant, do not have regular periods, as well as other circumstances, such as determining the status of menopause. You would only be postmenopausal if you no longer have periods at all.
