Useful For

Serum proteins transport drugs and metabolites and maintain plasma osmotic pressure. Most serum proteins are synthesized in the liver, with the exception of gamma globulins. One of the most important serum proteins produced in the liver is albumin. Total serum protein concentration can be used for evaluation of nutritional status.

Causes of high total serum protein concentration include dehydration, Waldenström’s macroglobulinemia, multiple myeloma, hyperglobulinemia, granulomatous diseases, and some tropical diseases. Total protein concentration is occasionally increased in collagen diseases, lupus erythematosus, and other instances of chronic infection or inflammation. Causes of low total serum protein concentration include pregnancy, excessive intravenous fluid administration, cirrhosis
