A semiquantitative microalbumin test is designed to provide an approximation of the levels of albumin in the urine, according to CLIAWaived.com and The Free Dictionary. If albumin shows up in the urine, it is a potential sign of kidney damage, according to Healthline.
Albumin is one of the proteins essential to health because the body uses it to repair tissue and spur normal cell growth. Kidney damage can allow the albumin to move from the bloodstream into the urine, which can result in severe health complications. The purpose of a semiquantitative microalbumin test is to determine the level of albumin in the urine, according to Healthline.
Frequently, the test for albumin also tests for creatinine to yield a ratio of albumin to creatinine, which is a waste product that healthy kidneys normally remove from the bloodstream. Kidney damage leads to a drop in creatinine levels and a possible increase in albumin levels. If undetected, kidney damage can progress to kidney failure. Recognizing the incidence of kidney damage in time allows for successful treatment or at least management of kidney disease to stave off kidney failure for as long as possible. Type 1 and Type 2 diabetics undergo this type of testing annually, as Healthline notes.
