This urine test measures very small amounts of a protein called albumin. Your liver makes albumin and your body uses it to grow and repair tissues and to help your body get rid of extra fluid.
This test is done to check for early signs of kidney damage, especially if you have diabetes.
A ratio of albumin (mcg/L) to creatinine (mg/L) of less than 30 is normal; a ratio of 30-300 signifies microalbuminuria and values above 300 are considered as macroalbuminuria. On a standard urine dipstick, 10-20 mg/dL is the minimal detection limit of protein.
