CDC 2000 stature-for-age percentile (ages 2-19).
Growth is a trajectory. One measurement is one point — a paediatrician interprets it alongside parental heights, puberty stage, and general health.
A height within the 3rd-97th percentile band sits in the CDC reference range for age and sex — where the vast majority of children fall.
Height is largely genetic. Consider the Mid-Parental Height tool alongside this one.
| Category | Range |
|---|---|
| Below 3rd percentile | < 3rd |
| Reference band | 3rd – 97th |
| Above 97th percentile | ≥ 97th |
Kidney Function & ElectrolytesUnderstand what creatinine and estimated GFR (eGFR) measure, why eGFR is a calculated estimate rather than a direct measurement, and why one result cannot diagnose chronic kidney disease on its own.
Kidney Function & ElectrolytesLearn what blood urea nitrogen (BUN) measures, why it can rise for reasons unrelated to kidney filtration, and why the BUN-to-creatinine ratio adds context a single BUN value can't.
Kidney Function & ElectrolytesLearn why urine albumin-to-creatinine ratio (uACR) can detect kidney damage before eGFR falls, how the A1/A2/A3 categories work, and what can cause a falsely elevated result.
Kidney Function & ElectrolytesLearn what cystatin C measures, why it's less affected by muscle mass than creatinine, and when guidelines recommend using it to confirm a borderline eGFR result.
A height within the 3rd-97th percentile band sits in the CDC reference range for age and sex — where the vast majority of children fall.
