Great test
Great test! I would recommend you take into consideration if a woman is in Perimenopause when rating sex hormone biometrics (ie we have erratic hormones that are not necessarily "out of range" and our cycles may not be regular anymore, hence we can't accurately tell you which stage we are in (follicular, ovulatory etc)

Zanoon, thank you for the thoughtful feedback. You’re absolutely right that perimenopause introduces significant variability in hormone levels, which makes it difficult to interpret results using standard cycle-based ranges. Because of that, we’ve intentionally avoided defining rigid perimenopausal ranges. Right now, selecting “other” is likely the most appropriate option rather than trying to assign a specific phase. Where testing can be useful in this stage is in tracking patterns over time. It helps connect how you’re feeling with what your hormone levels are doing, understand how interventions like HRT may be impacting you, and see how other systems respond to that variability. We’re actively working on better ways to support people in perimenopause, and this kind of feedback is incredibly valuable in shaping that.
