Helicobacter pylori Antigen, Stool

The ImmunoCard STAT HpSa is a rapid in vitro qualitative procedure for the detection of Helicobacter pylori antigens in human stool. The stool antigen detection is intended to aid in the diagnosis of H.pylori infection and to demonstrate loss of H.Pylori antigen following treatment. Conventional medical practice recommends that testing by any method to confirm loss of antigen be done at least four weeks following completion of therapy.

H.PYLORI AG,STOOL

Solid or formed, semisolid and liquid stool samples are acceptable.

Antimicrobials, proton pump inhibitors and bismuth preparations are known to suppress H. pylori, and ingestion of these prior to H. pylori testing (culture, histology, rapid urease, UBT, antigen) may cause false-negative results. If a patient has ingested these compounds within two weeks prior to performing the ImmunoCard STAT! HpSA test, a false-negative result may occur. In such cases, the test should be repeated on a new specimen obtained two weeks after discontinuing treatment. A positive result for a patient ingesting these compounds within two weeks prior to performing the ImmunoCard STAT! HpSA test, should be considered accurate.

2-8°C for 72 hrs or frozen at -20° for up to 14 days.
