Albumin/Albumin

An albumin blood test measures the amount of albumin in your blood. Albumin is a protein made by your liver. Low albumin levels can be a sign of liver or kidney disease or another medical condition. High levels may be a sign of dehydration.

An albumin blood test is used to check your general health and nutrition, 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 albumin pass from your blood into your urine (pee).
