How to Use This Calculator

Enter the patient's eGFR (mL/min/1.73m2) from a recent lab report.
Enter the urine albumin-to-creatinine ratio (UACR in mg/g): <30 normal, 30-300 moderate, >300 severe.
Enter the patient's age (years).
Read the CKD stage per KDIGO (G1 through G5) and the corresponding risk level (1-4).
Review the 5-year progression risk (%) and recommended monitoring frequency (times per year).
