Built for people who assess or follow pediatric growth:
From measurement to follow-up
PediaMetrics brings the full workflow together: enter measurements, catch possible errors, interpret results, and see how growth changes over time.
Add age, sex, weight, length or height, and head circumference where appropriate.
Flag unlikely values and possible entry mistakes before relying on the calculation.
See applicable Z-scores, percentiles, classifications, body metrics, and fluid estimates.
Plot saved measurements on interactive WHO curves to review growth across visits.
One structured workflow
A single measurement can answer an immediate question. Saved histories, charts, and reports make the result useful beyond the moment it was calculated.
Calculate applicable Z-scores, percentiles, and classifications for weight, height or length, weight-for-length or height, BMI, and head circumference.
Surface unlikely values and possible unit-entry mistakes before they obscure the result.
Save patient profiles and review measurements on interactive charts across multiple visits.
Export patient summaries, measurements, Z-scores, validation results, and eligible charts.
Review BMI, body surface area, and Holliday–Segar maintenance-fluid estimates in the same flow.
Beyond the chart
Review body mass index, body surface area, and maintenance-fluid estimates without switching tools or re-entering the same measurements.
Built for informed use
Health-related tools need more than polished screens. PediaMetrics makes its standards, data handling, and role explicit.
Assessments use the WHO 2006 Child Growth Standards and WHO 2007 reference for the appropriate ages and indicators.
