Women are wasting their time and money buying do-at-home menopause-testing kits, top UK doctors say.
The urine tests are not predictive enough to tell whether a woman is going through the phase when her periods will stop, they warn.
Results could cause anxiety and confusion, and might even contribute to unplanned pregnancies, says the British Menopause Society.
Manufacturers say the kits should never replace medical advice.
One company that makes them said the tests could help women worried about the perimenopause, when periods can become erratic.
