what is microalb,ur
[edit on Wikidata] Microalbuminuria is a term to describe a moderate increase in the level of urine albumin. It occurs when the kidney leaks small amounts of albumin into the urine, in other words, when there is an abnormally high permeability for albumin in the glomerulus of the kidney. Normally the kidneys do not filter albumin, so if albumin is found in the urine it's then a marker of kidney disease.
