Hormone testing in perimenopause? Not as useful as you might think. Because estrogen and progesterone fluctuate dramatically day to day, blood tests often provide little diagnostic value. A menopause-trained provider can diagnose perimenopause based on clinical symptoms, a thorough history, and by ruling out other potential causes. The key? Listening to the patient, recognizing the pattern, and providing evidence-based care. #menopause #perimenopause #drmaryclaire #thenewmenopause
