Albumin (Serum)

Clinical definition of the Albumin test
Albumin is the most abundant protein in the blood. It helps move many small molecules through the blood, including bilirubin, calcium, progesterone, and medications and keeps fluids from leaking out of blood vessels; nourishes tissues, and transports hormones, vitamins, and ions like calcium throughout the body and plays a vital role in tissue growth and healing. Albumin is made in the liver and extremely sensitive to liver damage. The concentration of albumin drops when the liver is damaged, when a person has a kidney disease that causes nephrotic syndrome, when a person is malnourished, has inflammation or is in a shock. Albumin levels are high when a person is dehydrated. Checking the level of albumin in the blood helps assess kidney and liver function. When the albumin levels drop in the blood, the person develops swelling in the ankles (pedal enema) or abdomen (ascites), fluid accumulation takes place in the lungs (pulmonary edema), leading to shortness of  breath. Albumin plays an important role in keeping the fluid from the blood from leaking out into the tissues. Since albumin is made by the liver, decreased albumin is a sign of liver disease.
