Perimenopause Blood Test
Apr 5, 2026
Perimenopause Blood Test
A perimenopause blood test measures FSH, oestradiol, and other hormones to help determine whether you're entering the menopause transition—a phase that can begin in your early 40s (or even late 30s) and last 4-10 years, causing irregular periods, hot flushes, mood changes, brain fog, and sleep problems that many women don't recognise as hormonal until they're tested. Knowing you're in perimenopause validates your experience and opens treatment options.
At Blood Test London, perimenopause testing costs from £295 with results in 2-3 days. A doctor always reviews every result.

Blood Test Challenges in Perimenopause
Important: Perimenopause is characterised by FLUCTUATING hormones.
Challenge | Implication |
|---|---|
FSH varies day to day | Single test may not capture the picture |
Oestrogen swings high and low | Can be normal one day, abnormal the next |
Tests may look "normal" | Despite clear symptoms |
Our approach: Interpret results with clinical picture, may recommend repeat testing, focus on symptoms + results together.
