What is the GFR for ESRD?

• A. > 90 mL/min/1.73 M2
• B. 30-59 mL/min/1.73 M2
• C. 15-29 mL/min/1.73 M2
• D. < 15 mL/min/1.73 M2

Answer: (D)

End-stage renal disease is defined by a glomerular filtration rate that falls below 15 mL/min/1.73 m^2. At this level of kidney function, waste products and fluids tend to accumulate, electrolytes become hard to balance, and most patients require renal replacement therapy, such as dialysis or a kidney transplant. The units mL/min/1.73 m^2 are standardized to body surface area. In the CKD staging framework, GFR above 90 is considered normal or high, 60–89 is mild, 30–59 is moderate to severe, 15–29 is severe, and below 15 marks ESRD.
