Quantification of sweat urea in diabetes using electro-optical technique.

Diabetic kidney disease is one result of prolonged elevation in blood glucose levels. When insulin secretion reduces, the serum urea level increases and vice versa is also true. Hence, monitoring urea level in blood is important in diabetic subjects. Any change in serum urea will have an impact on sweat urea concentration. Therefore, the proposed device can be used to measure sweat urea periodically, so that any change can be observed at an early stage and diabetic nephropathy could be prevented at large.
