Schwartz Pediatric eGFR

PediatricsNephrology

Medical context

Estimate pediatric GFR with the Schwartz bedside equation (k × height / creatinine).

Pediatric teams must confirm age-appropriate references and weight-based dosing with local protocols.

This page explains the Schwartz eGFR formula, how to interpret the output, known limitations, and peer-reviewed references so you can verify results against primary sources and local protocols.

It is grouped under Pediatrics because neonatal and pediatric medical calculators.

How to use this calculator

  1. Enter the values requested by the Schwartz eGFR calculator using the units shown beside each field.
  2. Review the calculated result and read the interpretation section before acting on the output.
  3. Check limitations and references if the result will change management, dosing, or disposition.
  4. Use the related calculators section when you need supporting values (for example electrolytes, weight, or complementary risk scores).

Schwartz bedside · k = 0.413

eGFR ≈ k × height(cm) / Scr(mg/dL). k=0.413 common with IDMS creatinine (CKiD).

Formula

eGFR ≈ k × height(cm) / Scr(mg/dL).

Interpretation

k=0.413 is commonly used with IDMS-traceable creatinine (CKiD bedside).

Limitations

Less accurate at extremes; confirmatory testing may be needed for dosing/transplant decisions.

Frequently asked questions

Adult vs Schwartz?
Use CKD-EPI for adults; Schwartz (or pediatric equations) for children.
Is the Schwartz eGFR result enough to make a treatment decision?
No. Calculators support medical decision-making but do not replace examination, shared decision-making, institutional protocols, or consultant input when stakes are high.
Does Calcmedical store the values I type in?
