What it measures
Where a blood-pressure reading falls within the standard categories — from normal through elevated and the stages of high blood pressure (hypertension) — using the systolic (top) and diastolic (bottom) numbers you enter in mmHg.
How it works
You enter a systolic and a diastolic value from a home or clinic monitor. The tool classifies the reading using the 2017 ACC/AHA blood-pressure guideline: Normal, Elevated, Stage 1, Stage 2, and the urgent Hypertensive Crisis range. It does not measure your blood pressure — it interprets a reading you already have.
Tips for an accurate result
- 1Average several readings — Take two or three readings a minute apart, on more than one day, and use the average — single readings vary a lot.
- 2Mind 'white-coat' rises — Blood pressure often reads higher in a clinic. Home readings over a week give a truer picture.
- 3Track the trend — One number matters less than the pattern over weeks. Keep a simple log to share with your GP.
- 4Lifestyle moves the numbers — Less salt, more activity, weight loss, limiting alcohol, and managing stress can all lower blood pressure measurably.
