Which of the following is the best early indicator for diabetic nephropathy? (AIIMS May 2014)
|C||Rising blood urea nitrogen|
a. Permanent renal damage can develop in as little as 5 years after diabetes mellitus.
b. The spilling of albumin into the urine and, more specifically, the spilling of very small levels of albumin ("microalbuminuria") are the best markers to date for significant diabetic nephropathy.
c. Hypertension often coexists with, and apparently favors the development of, microalbuminuria, but is not a specific marker for renal damage.
