34838: Helicobacter pylori Antigen, EIA Stool Print View
H. Pylori Antigen EIA  Not detected   

PRIMARY
1 Stool 0.5 (0.5) g   Refrigerated - 72 Hour(s)/Frozen - 30 Day(s)  
ALTERNATE

Colonization with H. pylori is associated with increased risk of patients developing gastritis, peptic ulcer disease, and gastric adenocarcinoma. Stool antigen testing provides a sensitive measure of infection including during and after treatment.

Patient preparation:
For initial diagnostic purposes no special patient preparation is
required. Patients are not required to be off of medications or to
fast before this test. While positive test results from patients
taking agents such as proton pump inhibitors and antimicrobials
should be considered accurate, false negative results may
be obtained. For this reason, physicians may suggest the patient
go off medications for two weeks and repeat test if negative results
are obtained. To confirm eradication, testing should be done at
least 4 weeks following the completion of treatment. However, a
positive test result 7 days post therapy is indicative of treatment
failure. This test is cleared for use with specimens from
pediatric patients.

Collect 0.5 mL or 0.5 grams of semi-solid stool or 20 mm diameter
solid stool and transfer to properly labeled plastic, leak-proof
container. Do not place stool in preservative, transport media
or swab. Watery, diarrheal stool is not acceptable.
