Helicobacter. Pylori Antigen Rapid Test is a corkscrew-shaped,
gram-negative rod that lives in the mucous layer of the stomach. H. pylori infection is now accepted as the most common cause of gastritis,
and is etiologically involved in gastric ulcer, duodenal ulcer,
gastric adenocarcinoma and primary gastric B-cell lymphoma.1,2 The organism is very common, infected at least
half of the world’s population. H. pylori infection is typically acquired in childhood. Once acquired,
infection persists chronically, probably continuing in the. stomach
throughout life. The damage to gastric structure and function of
stomach is constant and direct. Approximately one in six of H. pylori infection develops peptic ulcer disease and a small portion of H. pylori infection leads to gastric cancer.3 The diagnostic tests for H. pylori can be classified into two categories: Invasive and Noninvasive
tests. Direct detection by invasive test procedures requires an
endoscopy and biopsy specimens from antrum and stomach body.4 The
presence of H. pylori is then confirmed by direct culture, histological examination or
rapid urease test. The endoscopy and biopsy specimens offer direct
detection of active H. pylori infections. Although the procedure is highly specific and high
positive predictive value, the cost and discomfort to the patients
are very high. The most widely available noninvasive test is
probably the serological based test. The serology test detects H. pylori specific IgG antibody in patient serum with current or prior
infection.5,6 Serology test is a simple, convenient test with
relative high sensitivity. The main limitation of serology test is
the inability to distinguish current and past infections. Antibody
may be present in the patient’s serum long after eradication of the
organism.6 The urease breath test (UBT) with 14C or 13C labeled
urea, is a noninvasive test based on the urease activity of the
organism. UBT detects active H. pylori infection and is highly sensitive and specific. The UBT requires a
high density and active bacteria and should not be performed until
4 weeks after therapy to allow residual bacterial to increase to a
sufficient number for detection.7
H. pylori Antigen Test is an imunochromatographic assay that uses
antibody- coated colloidal gold to detect the presence of H. pylori antigens in stool specimens. The test detects directly antigens in
specimens for an active infection. The test is simple and easy to
perform and the test results can be visually interpreted within 15
minutes
