Microalbuminuria is the presence of a type of protein (albumin) in the urine. Normally, the filtration units in the kidneys (glomeruli) prevent the loss of the protein into the urine. However, with certain kidney diseases, including diabetic nephropathy, these units are damaged and become ‘leaky’. This ‘leak’ of protein in the urine is picked up during laboratory analysis of the urine, or with a dipstick, and termed microalbuminuria.
Your kidney specialist can determine the cause of the microalbuminuria. Individuals with microalbuminuria benefit from close monitoring of their general and kidney health with treatment to prevent further worsening of kidney function.
