Which value defines kidney failure (CKD stage 5)?

Which value defines kidney failure (CKD stage 5)?

• A. 15 mL/min/1.73 m² or dialysis, end-stage renal disease.
• B. 30 mL/min/1.73 m²
• C. 60 mL/min/1.73 m²
• D. 90 mL/min/1.73 m²

Answer: (A)

CKD stage 5, or kidney failure, is defined by an estimated GFR below 15 mL/min/1.73 m² or the need for dialysis (end-stage renal disease). This threshold shows that kidney filtering capacity has become very poor. Values like 30 or 60 mL/min/1.73 m² correspond to earlier CKD stages (moderate to severe loss of function), while around 90 mL/min/1.73 m² is normal kidney function. If a person requires dialysis, that also places them in stage 5 regardless of the exact eGFR. So the defining criterion is 15 mL/min/1.73 m² or dialysis.
