Child Blood-Pressure Screening

Classifies a child’s blood pressure per the AAP 2017 guideline: simplified screening thresholds for ages 1–12 and adult-aligned categories for 13+. This is a screening tool; it is not a diagnosis.

This tool is for information and screening only; it does not diagnose. Blood pressure must be measured with a correctly sized cuff, with the child rested and calm, on multiple occasions across different days. Definitive assessment uses full height-percentile tables by a clinician.

Frequently asked questions

Does this tool diagnose?

No. It is a screening tool that indicates whether a value warrants further evaluation. A diagnosis of hypertension requires repeated measurements on different days and full height-percentile tables, by a clinician.

Why are ages 1–12 and 13+ handled differently?

AAP 2017 uses adult-aligned fixed thresholds at 13+ (120/80 and the stages above). For ages 1–12, BP varies by age, sex and height, so a simplified screening table flags values needing further evaluation.

How is BP measured correctly?

Use a correctly sized cuff; the child should be rested for a few minutes, back supported and calm. A single high reading is not diagnostic — the average of two–three readings and repeats on different days matter.

It says “further evaluation” — should I panic?

No. It means the value exceeded the screening threshold and should be reviewed by a clinician; often a single reading or measurement conditions are involved. The right step is to consult your paediatrician.
