FAQ
What is eGFR?
eGFR (estimated Glomerular Filtration Rate) measures kidney filtering capacity. Normal is ≥90 mL/min/1.73m².
What are CKD stages?
G1:≥90 normal, G2:60-89 mild, G3a:45-59 mild-moderate, G3b:30-44 moderate-severe, G4:15-29 severe, G5:<15 kidney failure.
What is creatinine?
Creatinine is a muscle waste product filtered by kidneys. Elevated blood creatinine often indicates reduced kidney function.
How accurate is this calculator?
Uses CKD-EPI 2021 formula for adults. Reference only, not medical diagnosis. Consult a doctor.
