I've seen a lot of posters requesting blood tests or having had blood tests for confirmation of peri meno or menopause.
Just wanted to say that these are very unreliable- as my own test showed. Hormone levels in peri can change daily and show post menopause one day and highly fertile the next.
(Mine showed I was post meno when in fact I had periods for another 18 months.) I didn't have it for peri symptoms as such- more an overall hormone profile for another health issue.
The test needs to be done on days 3 and then around day 14 ( mid cycle) in one month. Even then it may need a re-run over 2-3 months.
I understand that many GPs don't know this and therefore women are getting false results.
If you have peri symptoms and other things are excluded - eg thyroid issues- then it's pretty sensible to assume it is peri and treat accordingly.
So if your tests come back and say you are not in peri but have all the symptoms, I'd take that with a pinch of salt!
