Microalbumin (Random)


Using a random sample, this test looks for albumin in urine, an early indicator of kidney failure. Albumin is a protein that is produced in the liver and is present in high concentrations in the blood. When the kidneys are functioning properly, no albumin will leak through the kidneys so there will be no detectable albumin in the urine. If the kidneys are damaged, small amounts of albumin leak into the urine, a condition known as microalbuminuria.

Early detection is critical in order to implement interventions that may preserve kidney function. Microalbuniuria is most often caused by kidney damage from diabetes. Health challenges such as high blood pressure, heart failure, cirrhosis, or systemic lupus erythematosus (SLE), however, can also threaten optimal kidney health.

Test Preparation For Optimal Results:

If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.
