Blood tests in the management of Helicobacter pylori infection. Italian Helicobacter pylori Study Group

摘要: There are three main types of blood test available for the management Helicobacter pylori infection: those that detect an antibody response ; tests pathophysiological state stomach; and indicate active infection. Enzyme linked immunosorbent assay (ELISA) based kits most numerous commercially tests. Originally used crude antigen preparations but many newer use a more purified preparation giving increased specificity lower sensitivity. The sensitivity, specificity, predictive values can also be affected by population under coexistent disease in patients. Near patient on either latex agglutination or immunochromatography. Generally, they have low sensitivities compared with laboratory Commerical western blotting been developed to presence specific virulence markers. exact role serology infection has still defined, although there is evidence that, as screening procedure, it reduce endoscopy cost workload. Gastrin pepsinogen concentrations may provide valuable information stomach-for example, inflammation gastric atrophy. A combination serum gastrin effectively serious gastroduodenal
