If your cycle feels different - shorter, heavier, missing altogether - blood tests can help make sense of what’s happening.
Here are 3 blood tests worth considering:
1. FSH (Follicle-Stimulating Hormone): Rises in perimenopause as the ovaries become less responsive. A better marker than one-off oestrogen or progesterone, which can fluctuate daily.
2. Iron studies: Heavy periods can deplete iron stores, leaving you fatigued and foggy.
3. Thyroid Panel: Because thyroid issues mimic perimenopause symptoms, it’s important to check.
Keep in mind: these numbers only make sense when viewed alongside your symptoms & give us so much more value when analysed against optimal ranges.
Start a cycle + symptom journal now so you can connect the dots when results come back.
PS - did you know that we can privately order blood tests for you if needed?
