Estimate kidney function using the Cockcroft-Gault equation. Requires your serum creatinine lab result.
Creatinine clearance estimates how well your kidneys filter waste from the blood. Normal CrCl is roughly 90 to 120 mL/min. Values below 60 may indicate reduced kidney function and warrant follow-up with a doctor.
CKD stages are based on GFR: Stage 1 is above 90, Stage 2 is 60 to 89, Stage 3 is 30 to 59, Stage 4 is 15 to 29, and Stage 5 (kidney failure) is below 15.
