it is shown that although purified c1q binds hsap , in the serum , the aaa and not c1q are responsible for the albumin binding activity in hbsag-negative sera of patients with liver disease and of normal individuals , as detected by passive hemagglutination of e-hsap , aaa were found to inhibit the binding of serum c1q to polymerized albumin , and hence the e-hsap hemagglutination test for aaa titration in human sera proved valid .
