If you’re considering or already taking hormone replacement therapy (HRT), you may wonder whether blood tests before or during HRT are necessary. The answer is nuanced: HRT is mainly started and adjusted based on your symptoms, not blood levels, but testing still has a useful role; both to check your wider health before starting and, in specific situations, to support monitoring.
Is a blood test needed to start HRT?
For most women over 45 with typical menopausal symptoms, HRT can be started based on symptoms alone, without a blood test. This is standard UK guidance, because hormone levels fluctuate so much during the menopause transition that a single test doesn’t necessarily reflect how you’re feeling or guide the decision any better than your symptoms do.
When testing is more relevant
- Under 45, or under 40 where premature menopause is a possibility; FSH testing is more informative here.
- Unclear or atypical symptoms, where other causes need to be ruled out first.
- Checking general health before starting: cholesterol, blood sugar, liver and thyroid function give useful baseline context, since HRT is a long-term treatment decision.
- Ruling out overlapping conditions, particularly thyroid problems, which share many symptoms with menopause.
Monitoring once you’re on HRT
Once established on HRT, most monitoring is based on how you feel and whether your symptoms have improved, alongside routine reviews with your prescriber. Hormone blood levels aren’t usually rechecked as a matter of routine for standard HRT, though your clinician may request specific tests in individual circumstances; for example if a dose isn’t having the expected effect, or with certain types or routes of HRT. Any changes to your prescription should always be guided by your GP or menopause specialist.
Wider health checks worth considering
Because HRT is often taken for several years, it’s sensible to keep an eye on the broader health markers that matter through midlife regardless of your HRT status; cholesterol and cardiovascular risk, blood sugar (HbA1c), liver function, and bone-related markers such as vitamin D. Our Menopause Bone & Heart Health Panel and Post-Menopause Annual Wellness Review are designed for exactly this kind of ongoing check.

Frequently asked questions
Do I need a blood test before starting HRT?
Not usually, if you’re over 45 with typical symptoms; HRT is generally started based on symptoms. Testing is more relevant under 45 or when the picture is unclear.
Will my hormone levels be checked regularly once I’m on HRT?
Not routinely for standard HRT; monitoring is mainly based on symptoms, though your clinician may request specific tests in individual cases.
Should I check my thyroid before starting HRT?
It can be useful, since thyroid problems cause similar symptoms to menopause and it’s worth ruling them in or out.
Can I get these tests done privately?
Yes; no GP referral is needed, though any decision to start, change or stop HRT should still be made with your GP or a menopause specialist.
How quickly will I get my results?
Most results are available within 1–2 working days and are reviewed by a GMC-registered doctor before you receive them.
