What to do with a 189 reading

Wait a minute and check again. If it is still above 180, call your doctor. Call 911 if you also have chest pain, shortness of breath, back pain, numbness, weakness, a change in vision or trouble speaking.

Readings move from minute to minute, and the first one usually runs a few points higher. The home measuring guide covers how to get a reading you can trust, and the 7-day home average turns a week of readings into the number your doctor uses. To check any reading, use the category checker.
