Estimate a child’s adult height from parental heights — Tanner mid-parental method.
A genetic-potential estimate — not a prediction. Actual adult height is influenced by nutrition, health, and puberty timing. Skeletal maturity determines the final answer.
This is the mid-parental estimate of the child’s eventual adult height (Tanner 1970), with a ± 8.5 cm range that captures roughly 95% of children.
Estimate, not a prediction. ± 8.5 cm captures ~ 95% of children (Tanner 1970).

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.
This is the mid-parental estimate of the child’s eventual adult height (Tanner 1970), with a ± 8.5 cm range that captures roughly 95% of children.
A paediatrician tracks the child’s current height percentile trajectory against this genetic target over time.
