Biohit launches new Helicobacter pylori IgA/IgG ELISA kit

Biohit launches a new Helicobacter pylori IgA/IgG ELISA kit (Cat. No. 601045). The kit is available for in vitro diagnostic use as of 16 October 2006. Since both human IgA and IgG antibodies to Helicobacter pylori (H. pylori) are detected in EDTA plasma and/or serum, the new test finds H. pylori infection more reliably. IgA and IgG antibodies are measured simultaneously from the same well.

The Helicobacter pylori IgA/IgG ELISA test is intended to aid in the diagnosis of H. pylori infection in adult patients with clinical symptoms of gastritis. The test is an enzyme-linked immunosorbent assay (ELISA) for the simultaneous detection of human IgA and IgG class antibodies to H. pylori in EDTA plasma and serum.

Helicobacter pylori IgA/IgG ELISA kit will be part of the GastroPanel test and will with immediate effect replace the Helicobacter pylori IgG ELISA kit (Cat. No. 601 040) that until now has been used in the panel.

Principle of the test and performance characteristics

Helicobacter pylori IgA/IgG ELISA kit is based on an enzyme immunoassay technique with partially purified H. pylori bacterial antigen absorbed on a microplate well and a detection antibody labeled with horseradish peroxidase (HRP).

Helicobacter pylori IgA/IgG ELISA kit compared to culture (N=997) showed the following characteristics:

Sensitivity 98%

Specificity 92%
