The H. pylori antibody test quantitative biochemical method is one of the commonly used clinical methods to measure the presence of H. pylori infection. Quantitative biochemical method for H. pylori antibody detection is a non-invasive test, which has the advantage of being convenient and quick, but cannot reflect the infection status of H. pylori in real time, because after H. pylori is eradicated, its serum antibody takes about 6 months to decrease or disappear, and at this time, a false-positive result will occur when the blood is drawn. H. pylori is a spiral-type bacterium that requires high growth conditions and is the only known microorganism that can live in the human stomach. It can be eradicated by triple or quadruple therapy. Patients are advised to undergo appropriate H. pylori tests under the guidance of a medical professional and should seek immediate medical attention for targeted treatment after infection with H. pylori to avoid delays.
