An albumin urine test measures the amount of albumin in your urine. High albumin levels can in urine be a sign of liver or kidney disease or another medical condition. Low levels may be a sign of dehydration.
Albumin is a protein made by your liver. Albumin enters your bloodstream and helps keep fluid from leaking out of your blood vessels into other tissues. It is also carries hormones, vitamins, and enzymes throughout your body. Without enough albumin, fluid can leak out of your blood and build up in your lungs, abdomen (belly), or other parts of your body.
An albumin Urine test is used to check your general health and to see how well your liver and kidneys are working. If your liver is damaged or you’re not well nourished, your liver may not make enough albumin. If your kidneys are damaged, they may let too much albumin leave your body in urine (pee).
An albumin urine test is often done as part of a group of urine tests that measure different enzymes, proteins, and other substances made in your liver. These tests are called liver function tests or liver panel. An albumin test may also be part of a comprehensive metabolic panel (CMP), a group of routine urine tests that measures several substances.
