Menopause blood test: what to know

Menopause is a transition, so hormone levels can vary and one result may not represent the whole picture. A clinician may consider cycle changes, hot flushes, sleep disruption, vaginal symptoms, mood and contraception alongside examination. Testing can be more useful when symptoms are unusual, periods have stopped for another reason, menopause occurs earlier than expected, or another illness is possible. Blood tests may investigate anaemia, thyroid problems, kidney function or inflammation rather than prove menopause itself. Chronic fatigue syndrome, coeliac disease, Crohn's disease and glandular fever can cause tiredness or other overlapping symptoms. Brucellosis and dengue fever may be considered when illness and exposure history fit.

Before an appointment, record period dates, contraception, flushes, sleep, mood, vaginal symptoms, medicines and the concern that prompted testing. Ask whether any medicine or hormonal contraception could affect interpretation. Do not stop prescribed treatment before a test unless the clinician tells you to. A blood sample is usually taken from a vein; the team will explain preparation if a particular test requires it. Results are interpreted with your symptoms and history, not in isolation. If the aim is to investigate fatigue, mention weight change, fever, bowel symptoms, thirst, breathlessness or changes in urine.

Arrange medical review for unexplained tiredness, persistent fever, unplanned weight change, heavy or prolonged bleeding, bleeding after periods have stopped, or symptoms that interfere with daily life. Seek urgent help for severe weakness, fainting, chest pain, significant breathlessness, confusion, or heavy bleeding with dizziness. A test cannot replace assessment when symptoms are severe or rapidly worsening.

Do my symptoms need a menopause blood test or another investigation? Could contraception or medicines alter the result? What will the sample assess, when will results be reviewed, and what symptoms should I report sooner?
