KDIGO Heat Map for CKD Prognosis
KDIGO (Kidney Disease Improving Global Outcomes) prognosis grid for CKD using GFR and albuminuria categories. Identifies low, moderate, high, and very high risk of CKD progression.
Score interpretation
G1–G2 with A1. If there are no other markers of kidney damage, this is not CKD.
→ If CKD (other markers of kidney damage present): eGFR and ACR at least once a year (KDIGO); manage cardiovascular risk.
G1–G2 with A2, or G3a with A1.
→ eGFR and ACR at least once a year; blood pressure to target; ACE inhibitor / ARB if albuminuric with diabetes or hypertension; review nephrotoxic drugs.
G1–G2 with A3, G3a with A2, or G3b with A1.
→ eGFR and ACR about twice a year; RAS blockade and an SGLT2 inhibitor where indicated; ACR ≥ 30 mg/mmol (A3) is a KDIGO criterion for nephrology referral.
G3a with A3, G3b with A2–A3, or G4–G5 with any albuminuria.
→ eGFR and ACR 3–4 or more times a year; nephrology care (eGFR < 30 is a referral criterion); plan for kidney failure (dialysis, transplant or conservative care) as eGFR falls.
Interpretation bands for the KDIGO CKD Risk. Apply clinical judgement and local guidance.
