Glycoprotein acetyls  

Glycoprotein acetyls (GlycA) is a composite inflammatory marker that is elevated in both acute and chronic inflammation, neoplasia, and hyperlipidemia. It combines the N-acetyl group signals of the acute phase glycoproteins alpha-1-acid glycoprotein, alpha-1-antitrypsin, haptoglobin, transferrin, alpha-1-antimymotrypsin, and glycosylated lipoproteins. The rise in GlycA can be caused either by the increased abundance of these molecules or their glycosylation.
