Qualitative result for IgG
1 - 3 days
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.
0.5 mL (Note: This volume does not allow for repeat testing.)
Red-top tube, gel-barrier tube, or serum transfer tube
Maintain specimen at room temperature.
Non-serum samples; heat-inativated serum; grossly hemolyzed; icteric or lipemic; samples containing particulate matter or exhibiting obvious microbial contamination
The qualitative determination of IgG antibodies to Helicobacter pylori (H. pylori) in human serum from symptomatic adults as an aid in the diagnosis of H. pylori infection.
Assay results should be utilized in conjunction with other clinical and laboratory data to assist the clinician in making individual patient management decisions. Heterophilic antibodies in human serum can react with reagent immunoglobulins or other reagent material, interfering with in vitro immunoassays.
This assay has not been evaluated in a pediatric population.
This assay should be used only to evaluate patients with clinical signs and symptoms suggestive of gastrointestinal disease and is not intended for use with asymptomatic patients.
A positive test result does not allow one to distinguish between active infection and colonization by H. pylori. A positive test only indicates the presence of IgG antibody to H. pylori and does not necessarily indicate that gastrointestinal disease is present.
A negative test indicates that IgG antibody to H. pylori is not present or is at a level that cannot be detected by the assay.
Chemiluminescence immunoassay (CLIA)
• Negative: <0.80
• Equivocal: 0.80 - 0.89
• Positive: >0.89
