Table 1.

Chronic kidney disease (CKD) staging based on the glomerular filtration rate (GFR).

CKD stage / GFR category	GFR (ml/min/1.73 m²)	Terms
G1	≥90	Normal or high
G2	60-89	Mildly decreased
G3a	45-59	Mildly to moderately decreased
G3b	30-44	Moderately to severely decreased
G4	15-29	Severely decreased
G5	<15	Kidney failure

If no evidence of kidney damage, neither GFR category G1 nor G2 fulfill the criteria for CKD.
