Overview
Microalbumin levels in the urine is an excellent tool to look for early damage to kidneys secondary to diabetes. Albumin is a protein found normally in the serum, but it gets completely absorbed from the renal tubules when it is filtered into the nephron from the glomerulus. Hence, a damaged nephron will not reabsorb the albumin filtered by the glomerulus and it appears in the urine.
Screening
- Screening for nephropathy in diabetes should begin at the time of diagnosis of type II diabetes mellitus, since about 7% of patients may have damaged kidneys even in early stages of diabetes.
- Minute levels of albumin (microalbuminuria) in the urine are not detectable with routine urine protein dipsticks.
- The incidence of diabetic nephropathy may particularly increase in patients with poor glycemic control, systemic hypertension and hyperlipidemia.
- If microalbuminuria is not present, the test must be repeated annually for both type I and type II diabetes mellitus patients.
