Clinical Utility

Alpha-1-acid glycoprotein is an acute phase reactant whose role is unknown. Early work indicated that the liver is the only site of synthesis, but more recent studies have shown that some tumors are also able to synthesize it. Clinically, alpha-1-acid glycoprotein is used for monitoring acute phase reactions such as inflammatory conditions, rheumatoid arthritis, and malignant neoplasms.
