A progressive condition characterized by gradual loss of kidney function over months or years, classified into 5 stages based on eGFR.
CKD is defined as kidney damage or GFR <60 mL/min/1.73m² for ≥3 months. The five stages are: Stage 1 (GFR ≥90, kidney damage), Stage 2 (GFR 60-89), Stage 3a (GFR 45-59), Stage 3b (GFR 30-44), Stage 4 (GFR 15-29), and Stage 5 (GFR <15, kidney failure). Common causes include diabetes, hypertension, and glomerulonephritis. Management focuses on slowing progression through blood pressure control, RAAS blockade, SGLT2 inhibitors, dietary modifications, and treating complications like anemia and mineral bone disease. Early detection and structured monitoring are critical — ZuvFlo's CKD staging engine automates eGFR calculation and progression tracking.
A calculated value estimating the rate at which kidneys filter blood, used to diagnose and stage chronic kidney disease.
The final stage of chronic kidney disease (Stage 5, eGFR <15) where kidneys can no longer sustain life without dialysis or transplantation.
The medical specialty focused on the diagnosis, treatment, and management of kidney diseases, including dialysis and transplant care.
Abnormal presence of protein in the urine, a key marker of kidney damage and the strongest predictor of CKD progression and cardiovascular risk.
