Clinical Information
Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Helicobacter pylori is well recognized as the cause of chronic active gastritis, duodenal ulcer, and nonulcer dyspepsia.
Currently accepted methods for the diagnosis of Helicobacter pylori infection include serologic tests, the urea breath test (UBT), and culture or histologic examination or direct urease testing (CLO test) of biopsy specimens obtained at the time of gastroduodenoscopy (ENDO). Each of these tests has its drawbacks, including lack of specificity (serology) or high cost, complexity, and inconvenience for the patient (UBT and ENDO).
See Helicobacter pylori Diagnostic Algorithm in Special Instructions.
Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
Negative
Interpretation
Provides information to assist in interpretation of the test results
Positive results indicate the presence of Helicobacter pylori antigen in the stool.
Negative results indicate the absence of detectable antigen but does not eliminate the possibility of infection due to Helicobacter pylori.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
Stool must be mixed thoroughly to ensure representative sampling.
This is a qualitative, not a quantitative, test.
Falsely negative results may be obtained within 2 weeks of treatment with antimicrobials, bismuth, or proton pump inhibitors. A negative test result in such a situation should be followed up with a repeat test at least 2 weeks after discontinuing therapy.
Interfering Substances: The following substances that may be present in human stool, DO NOT interfere with positive or negative test results at the stated concentrations per 500 microliters of human stool: TUMS (10 mg), Mylanta (0.84 mg), Pepto Bismol (0.35 mg), Tagamet (1 mg), Prilosec OTC (1 mg), barium sulfate (10 mg), whole blood (100 microliters), mucin (6.7 mg), human hemoglobin (ie, dark stool) (15 mg), steric + palmitic acids (ie, fatty stool) (7.9 mg).
Performance characteristics of the test have not been established for watery, diarrheal stools.

Method Description
Describes how the test is performed and provides a method-specific reference
The ImmunoCard Helicobacter pylori stool antigen test consists of a chromatography strip housed in a plastic frame and enclosed in a foil pouch with a desiccant. The strip carries monoclonal anti-H. pylori capture antibody for the test and an animal protein for a control. The strips also contain red-latex conjugated anti-H. pylori and blue latex-conjugated anti-protein as the detector antibodies for tests and controls, respectively.(ImmunoCard STAT HpSA, Meridian Bioscience, Inc., Cincinnati, Ohio , 2003)

Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
Monday through Saturday
Report Available
The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.
Specimen Retention Time
Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
Performing Laboratory Location
