H. pylori IgM ELISA Kit Background Information
Helicobacter pylori is a spiral bacterium cultured from human gastric mucosa identified by Marshall in 1982. Studies have indicated that the presence of H. pylori is associated with a variety of gastrointestinal diseases including gastritis, duodenal and gastric ulcer, non-ulcer dyspepsia, gastric adenocarcinoma and lymphoma. The organism is present in 95-98% of patients with duodenal ulcer and 60-90% of patients with gastric ulcers. Multiple studies have also demonstrated that removal of the organism by antimicrobial therapy is correlated with the resolution of symptoms and cure of diseases. Patients who present with clinical symptoms relating to the gastrointestinal tract can be diagnosed for H. pylori infection by two methods:
1. Invasive techniques include biopsy followed by culture or histologic examination of biopsy specimen or direct detection of urease activity
2. Non-invasive techniques include urea breath tests and serological methods. Serologic tests are employed to detect antibodies as human immune response to H. pylori. Two methods appear to be of great interest regarding their use in H. pylori routine serology, namely the ELISA and the Western immunoblot because they offer the most versatility in regards to immunoglobulin specificity and relative ease of use.


H. pylori IgM ELISA Test Principle
Purified H. pylori antigen is coated on the surface of microwells. Diluted patient serum is added to wells and H. pylori IgM specific antibody, if present, binds to the antigen. All unbound materials are washed away. After adding enzyme conjugate, it binds to the antibody-antigen complex. Excess enzyme conjugate is washed off and TMB Chromogenic substrate is added. The enzyme conjugate catalytic reaction is stopped at a specific time. The intensity of the color generated is proportional to the amount of IgM specific antibody in the sample. The results are read by a microwell reader compared in a parallel manner with calibrator and controls.


H. pylori IgM ELISA Test Results Interpretation
Negative: H. pylori M Index of 0.90 or less are seronegative for IgM antibody to H. pylori.
Positive: H. pylori M Index of 1.00 or greater are seropositive. For additional details please refer to the instructions for use.


Precaution with H. pylori IgM ELISA Kit
The calibrator and controls contain human source components which have been tested and found
Non-reactive for hepatitis B surface antigen as well as HIV antibody with FDA licensed reagents. However, these reagents should be handled at the Biosafety Level 2.
