A urine albumin test checks the levels of albumin in the urine because abnormal amounts of this protein can be a sign of kidney problems. Several methods exist for measuring urine albumin including a urine dipstick, a one-time urine sample that compares the ratio of albumin to creatinine, and a 24-hour urine collection.
