Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Diagnose early H pylori infection in patients with gastric and duodenal disease. Circulating antibodies to H pylori are predominantly of the IgG class. A systemic response of the IgA type is usually less pronounced but, if significant, may indicate a more severe inflammation. A few patients develop only antibodies to IgA. Antibodies to IgM, although rare, may indicate an early infection.
This test was developed, and its performance characteristics determined, by LabCorp. It has not been cleared or approved by the US Food and Drug Administration (FDA). Results of this test are for investigational purposes only. The results should not be used as a diagnostic procedure without confirmation of the diagnosis by another medically diagnostic product or procedure.
Enzyme-linked immunosorbent assay (ELISA)
• Negative: <9.0 units
• Equivocal: 9.0−11.0 units
• Positive: >11.0 units
Current studies suggest that H pylori IgM testing should be performed concomitantly with IgA and IgG tests for associated diagnosis of H pylori.
