Test Overview. A microalbumin test checks urine for the presence of a protein called albumin. Albumin is normally found in the blood and filtered by the kidneys. When the kidneys are working properly, albumin is not present in the urine.But when the kidneys are damaged, small amounts of albumin leak into the urine. A blood test to check creatinine levels is often done with a microalbumin urine test. 2  To learn more, see the topic Creatinine and Creatinine Clearance. 3  A less precise test, the urine dipstick test, can be used to check for microalbuminuria in a single sample of urine.
High levels of microalbumin in urine may indicate kidney disease, but it may also be caused by medications, urinary tract infection and fever, according to Mayo Clinic. High levels of creatinine in a urine clearance test may indicate kidney disease, pregnancy, hypothyroidism or carbon monoxide poisoning, according to WebMD. Keep Learning.
