The normal amount of microalbumin in urea is 30 milligrams or less, states Mayo Clinic. A microalbumin test measures the amount of albumin present in the urine during a 24-hour period. Values between 30 and 300 milligrams indicate early kidney disease, and results above 300 milligrams suggest advanced kidney disease.Continue Reading
Albumin is a protein that is present in the blood and is filtered by the kidneys, explains WebMD. Healthy kidneys retain albumin, and only a trace amount of it is present in the urine. When kidney damage occurs from diseases such as diabetes, hypertension, heart failure, cirrhosis and systemic lupus erythematosus, large quantities of albumin spill into the urine. The most common cause of albuminuria is kidney damage caused by diabetes.
About one in every three people with diabetes has a significant amount of albumin present in his urine, and a yearly test is recommended for everyone with the disease, according to the National Kidney Foundation. The presence of urine albumin in people with diabetes is associated with a rapid progression of chronic kidney disease and potential kidney failure. Progression of kidney disease is controlled with medications that include ACE inhibitors and angiotensin receptor blockers. Prevention of kidney disease and other diabetic complications includes tight glucose control, blood pressure control, and smoking cessation.Learn more about Medical Ranges & Levels
