A urine albumin-to-creatinine ratio above which value is used as part of the thresholds for severe CKD?

• A. 150 mg/g
• B. 250 mg/g
• C. 300 mg/g
• D. 500 mg/g

Answer: (C)

Albuminuria is a key marker of kidney damage and helps gauge CKD severity. The urine albumin-to-creatinine ratio is categorized to reflect how much albumin leaks into the urine: normal-to-mild is under 30 mg/g, moderately increased is 30–299 mg/g, and severely increased is 300 mg/g or higher. Crossing 300 mg/g places someone in the severely increased albuminuria category (A3), which influences CKD risk stratification and prognosis. So the value that defines the threshold for severe CKD is 300 mg/g. Values like 150 or 250 mg/g are still in the moderately increased range, while a value like 500 mg/g, though severe, is understood within the same severe category and the cutoff used to define the threshold is 300 mg/g.
