GFR for stage 3 kidney damage with moderate low GFR?

• A. > 90 mL/min/1.73 M2
• B. 60-80 mL/min/1.73 M2
• C. 30-59 mL/min/1.73 M2
• D. 15-20 mL/min/1.73 M2

Answer: (C)

A moderate decrease in GFR places you in stage 3 CKD. This stage covers roughly 30 to 59 mL/min/1.73 m^2, with a subdivision into 3a (about 45–59) and 3b (about 30–44) in some guidelines. The key idea is that this range reflects a meaningful but not extreme decline in kidney function, where there’s still some filtration left but with increased risk of complications and greater need for monitoring and management. Values above normal or near-normal (roughly ≥60) are not CKD or are only mild decreases, while values much lower (below about 30) point toward stage 4 or worse. Therefore, the moderate-low GFR described fits the 30–59 range.
