Your body will produce antibodies against H.pylori in the stomach. The test
is targeted on the antibody in your blood. The assumption is that H.pylori
infection will not disappear without treatment.
However, like any test, it has its limitation. The test is ~90% sensitive (
10% false negative) and 90% specificity (10% false positive). Since your
antibody will persist after the eradication of H.pylori, this test cannot
evaluate reinfection after treatment. |
