Severely increased albuminuria in diabetic nephropathy is defined as which?

• A. >300 mg/g albuminuria
• B. Albuminuria less than 30 mg/g
• C. Not measured
• D. Low GFR not related to albuminuria

Answer: (A)

In diabetic nephropathy, the amount of albumin leaking into the urine reflects the extent of glomerular injury and helps stage kidney disease. Severely increased albuminuria is defined by an albumin-to-creatinine ratio above 300 mg per gram, which is known as macroalbuminuria. This level indicates more advanced kidney damage and higher risk for progression and cardiovascular events. By contrast, albuminuria under 30 mg/g is normal, and 30–300 mg/g is microalbuminuria. The other options don’t describe a level of severe albumin leakage, and one option isn’t a measurement at all while another conflates GFR with albuminuria.
