What is Which of the following tests is most suited for early detection of diabetic nephropathy? and explain in detail?
The earliest change in diabetic nephropathy is microalbuminuria which coincides with the pathological changes which include thickening of the glomerular basement membrane and accumulation of matrix material in the mesangium. Microalbuminuria is defined as 30-299 mg/d of albumin in a 24-h urine collection. It is a good predictor of progression to nephropathy in Type 1 DM. It is less reliable predictor in elderly with Type 2 DM as it may be secondary to factors unrelated to DM, such as hypeension, congestive hea failure (CHF), prostate disease, or infection.
