SAA, Amyloid Protein
A serum protein believed to be a circulating precursor to amyloid protein AA. It is present in low concentrations in normal sera, but found in much higher concentrations in sera of older persons and in patients with amyloidosis or with diseases known to predispose to amyloidosis. Very high levels of this protein have been reported during acute inflammatory episodes. Antisera to amyloid protein AA cross-react with protein SAA.
