Specific Proteins - Alpha-I-Acid Glycoprotein

Alpha-I-acid-glycoprotein (also known as Orosomucoid) is an acute-phase reactant synthesised in the liver in response to inflammation and tissue damage. The normal range for healthy individuals is 50-120 mg/dl. However, markedly higher levels are observed in a number of conditions such as inflammatory disease, acute myocardial infarction, trauma, pregnancy and surgery. Serum AAG levels also provide a useful diagnostic tool in neonates with bacterial infections as most infected neonates produce increased levels.
