Clinical Evaluation of a Novel Stool Antigen Test Using Bioluminescent Enzyme Immunoassay for Detecting Helicobacter pylori

Figure 2

Dilution tests of 9 dissociated samples between B (EIA) and Q (IC). All samples almost showed linearity, without the characteristics seen in the nonspecific reaction (a). Helicobacter pylori antigen cutoff values for 9 samples without dilution ranged from 1.3 to 87.4 on (b) (EIA). Hp Ag, Helicobacter pylori antigen; COI, cutoff index.
