Understanding GFR

Glomerular Filtration Rate (GFR) measures how well your kidneys filter waste from your blood. It's the best overall measure of kidney function and is used to diagnose and monitor chronic kidney disease.

GFR categories:

  • Normal: 90+ mL/min/1.73m²
  • Mild decrease: 60-89 mL/min/1.73m²
  • Moderate decrease: 30-59 mL/min/1.73m²
  • Severe decrease: 15-29 mL/min/1.73m²
  • Kidney failure: <15 mL/min/1.73m²
