What is the eGFR range for CKD stage 3 (moderate decrease)?

• A. 30-59 mL/min/1.73 m².
• B. 15-29 mL/min/1.73 m².
• C. 60-89 mL/min/1.73 m².
• D. 90-120 mL/min/1.73 m².

Answer: (A)

eGFR staging uses filtration rate ranges to classify CKD. A moderate decrease in kidney function corresponds to CKD stage three, which is defined by an eGFR in the range of thirty to fifty-nine mL/min/1.73 m². This reflects a noticeable drop in kidney function where filtering is still present but not normal. Values higher than this indicate milder disease or normal function with markers of kidney damage, while values lower indicate more advanced CKD (stages four or five). Therefore, the range from about thirty to fifty-nine mL/min/1.73 m² best fits stage three.
