At a glance
Blood tests do not diagnose perimenopause or menopause in women over 45. Hormone levels fluctuate from day to day. Doctors usually assess symptoms and menstrual changes, using tests when another cause or an earlier menopause needs investigation.[1]
Is there a way to test perimenopause?
A single FSH or oestradiol result cannot reliably establish the stage of perimenopause. The Australasian Menopause Society recommends clinical assessment at the usual menopause age. A result inside the laboratory range does not rule out symptoms linked to the transition.[1]
Can a GP do a blood test for perimenopause?
A GP can decide whether testing would answer a useful question. Jean Hailes explains that blood tests may check general health or investigate another cause of symptoms. Under 45, irregular or absent periods may warrant hormone investigations. The purpose of the test should be clear before collection.[2]
FSH, oestradiol and related investigations
FSH is a pituitary hormone involved in ovarian function. Oestradiol is an oestrogen. RCPA notes that FSH reference intervals depend on the method and menstrual cycle. The doctor interprets any requested markers together with your history. More markers do not automatically make an assessment more useful.[3]
Checking other explanations
Your doctor may consider pregnancy or thyroid disease when periods change, and other investigations where the history calls for them. Tell the doctor about your cycle, contraception and medicines. The appropriate tests depend on the question being investigated; this page does not prescribe a standard panel for everyone.[10]
Before booking a panel
Ask what each test is intended to investigate and whether existing reports can be used. Check whether the quote covers the initial doctor appointment, laboratory collection, all requested markers and a results discussion. Ask who receives the report and what happens if another appointment is needed.
Use the fee comparison with the clinical question
