A monitoring aid, not a diagnosis. For accurate readings, avoid caffeine, smoking or exercise just before, sit correctly and keep still. A single high reading is not the whole picture. Track readings over time and discuss them with your doctor; do not change your medicines based on home readings without advice. Seek urgent care for a very high reading with symptoms like chest pain, severe headache or breathlessness. Use the correct cuff size.
