What is the CKD staging system?

KDIGO stages G1-G5 by eGFR and A1-A3 by albuminuria (ACR). Green=low risk, yellow=moderately increased, orange=high, red=very high, dark red=highest risk.

When does CKD become dialysis-requiring?

Stage 5 (eGFR <15) typically requires preparation for renal replacement therapy. Symptoms guide timing of initiation.

How often should CKD be monitored?

Low risk: annually. Moderate risk: every 6 months. High risk: every 3 months. Very high risk: every 1-3 months.
