Stage 3a vs Stage 3b CKD: eGFR Ranges, Progression Risks, and Key Differences
The short answer: Stage 3 Chronic Kidney Disease (CKD) means your kidneys have moderate damage and are not filtering blood as efficiently as they should. Stage 3 is split into two substages based on your estimated glomerular filtration rate (eGFR): Stage 3a (eGFR 45–59) represents mild-to-moderate loss of function, while Stage 3b (eGFR 30–44) represents moderate-to-severe loss. Moving from Stage … Read more
