CDC 2000 BMI-for-age percentile (ages 2-19).
Growth is a trajectory over time. A single measurement is one datapoint — a paediatrician interprets it alongside height, family history, and health context.
A BMI between the 5th and 85th percentile sits within the CDC healthy-weight band for age and sex — the reference range for most children.
CDC 2000 LMS-derived percentile. Trajectory over time is more informative than a single point.
| Category | Range |
|---|---|
| Underweight | < 5th percentile |
| Healthy | 5th – 84th percentile |
| Overweight | 85th – 94th percentile |
| Obesity | ≥ 95th percentile |
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.
