Albumin is the smallest protein molecule in our blood and every single albumin in it is produced in the liver. It is a sensitive indicator of liver and kidney function.

Albumin is one of the smallest and most abundant proteins found in the human body. It is made by the liver and its main function is to maintain the fluid balance within the body. Albumin is required to prevent the leaking of fluid out of blood vessels and helps to transport molecules, like hormones, vitamins and drugs, around the body. Because albumin is made in the liver, its production is disrupted when there is a disease process in the liver. For example, albumin levels drop when there is liver cirrhosis. Also, to ensure that albumin is not constantly being lost in the urine since it is such a small protein, the kidneys need to be efficient at reabsorbing and preventing loss of albumin. If there is kidney disease, this process will be inadequate and the levels of the protein can drop.

• Malnutrition
