Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease, with hitherto unknown origin. It ranges from a mild disease course, to progressive hepatitis with fatal outcome.

Antibodies against the asialoglycoprotein receptor (ASGPR) are described in approximately 80 % of all patients with active AIH of types I or II. In contrast to other liver specific autoantibodies, antibodies against ASGPR are a marker of histological activity of liver disease. During therapy with corticosteroids, anti-ASGPR can be used for therapeutic monitoring.

  • The only commercially available ELISA with highly purified ASGPR from rabbit liver
  • Anti-ASGPR is the only organ specific autoantibody in autoimmune liver disease
  • Anti-ASGPR allows the serological follow-up of AIH
  • Anti-ASGPR allows a differential diagnosis, to rule out toxic and other inflammatory liver diseases.

Anti-ASGPR is an enzyme immunoassay for the semi-quantitive determination of IgG antibodies against the membrane receptor of asialoglycoproteins in human serum or plasma. The analytical sensitivity is a binding index (BI) of 0.3. The diagnostic specificity, identified from a cohort of healthy blood donors, is 100 %. The values for intra- and interassay precision are in the range of 5 - 9 % (coefficient of variation).
