eGFR — Stage G3a

eGFR 50 mL/min/1.73mÂ²: What It Means

Classification: Stage G3a

eGFR 50 is stage G3a CKD — roughly half of kidney function is lost. Many people feel nothing at this stage; that's why testing matters.

About the eGFR test

Estimated glomerular filtration rate — the best overall measure of kidney function. It is calculated from creatinine, age, and sex (CKD-EPI 2021 equation) and used to stage chronic kidney disease.

Calculated from a serum creatinine blood test. No extra sample needed — labs report eGFR automatically with any creatinine.

Reference: KDIGO CKD classification; CKD-EPI 2021 equation (NEJM 2021) • Normal range: â‰¥90 mL/min/1.73mÂ² (declines with age)

Use the eGFR tool

Calculate and interpret your value properly
