Pediatric GFR Calculator (Bedside Schwartz)

Health

The Pediatric GFR Calculator estimates a child's glomerular filtration rate using the bedside Schwartz equation from height and serum creatinine.

Formula

eGFR = 0.413 × Height (cm) ÷ Serum Creatinine (mg/dL)
  • The bedside Schwartz equation is validated for children with creatinine measured by IDMS-traceable methods.
  • It is a screening estimate, not a definitive measure of kidney function.

Height 120 cm, creatinine 0.5 mg/dL

Inputs
  • Height: 120 cm
  • Serum Creatinine: 0.5 mg/dL

0.413 × 120 ÷ 0.5 = 99 mL/min/1.73m².

Frequently asked questions

What is the bedside Schwartz equation?
A simple pediatric GFR estimate: 0.413 × height in cm divided by serum creatinine in mg/dL.
