What to do with a 107 reading

Keep checking now and then, the same way each time. Your category comes from the average of many home readings, so one number tells you less than a week of them.

With a bottom number of 80 or higher, the reading is at or above 130/80. In that case: sit quietly for 5 minutes and take two readings a minute apart. If home readings average in this range over a week, share them with your doctor, who will look at them alongside your overall heart risk.

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.
