found out my endo has been using an updated diagnostic standard i didn’t even know existed. the 2023 international PCOS guideline update lets AMH bloodwork stand in for the ultrasound criteria in adults, on top of the old rotterdam stuff (irregular cycles, androgens, polycystic ovaries on ultrasound). my endo pulled my AMH last year, 6.8 ng/mL, high enough on its own to satisfy the ovarian criteria without another transvaginal scan. i didn’t clock that this was a policy change until i went looking for why she skipped it this round when my GP always ordered one. practical part: if you’re waiting on a scan slot or your cycles are so irregular the timing keeps missing, ask if AMH is an option where you are. it’s one blood draw, no cycle-day timing needed, none of the “come back on day 3” runaround. doesn’t fix the diagnosis lag on its own. my GP was still running the day-21 progesterone standard on a 40-day cycle for months before any of this came up. but it’s one less hoop if your specialist actually knows the update exists. fwiw anyone had a doc mention AMH as a diagnostic swap, or are they all still defaulting to the scan?
