Is This Blood Pressure Normal?

The kidneys and blood pressure are closely linked. When the kidneys aren't filtering well, blood pressure can rise — and persistently high blood pressure puts extra strain on the kidneys in return. That's why nephrologists check blood pressure at every single visit. In children, "high" is not one fixed number — it depends on age, sex, and height, which is what this tool accounts for.

Enter your child's age, sex, height, and blood pressure reading. We'll show you where it falls compared to other children their age, based on published percentile tables.

Results are based on the AAP 2017 Clinical Practice Guideline for Screening and Management of High Blood Pressure in Children and Adolescents — the standard pediatric nephrologists use at every visit.
