The blood contains two major groups of protein: Albumin and Globulin. Albumin is made in the liver and makes up approximately 60% of the total protein. Since Albumin is produced in the liver, it is used as a measure of liver function as well as overall nutrition. One of the key functions of albumin is to prevent the abnormal movement of fluid from the bloodstream into the body's tissues. In addition, Albumin helps to transport medications and other substances through the blood.
Globulin is made up of several different types of protein. Globulin can be divided into three main groups: alpha-, beta- and gammaglobulin. Gammaglobulins are antibodies. Antibodies are proteins produced by the immune system to fight infection. For additional and more complete information regarding Blood Proteins, the following websites are recommended:
