A simple antibody test may be as effective in detecting Helicobacter pylori infection as more invasive procedures now being used.
Researchers from the University of Würzburg in Germany reported in the December issue of the Journal of Clinical Microbiology on the sensitivity of H pylori–specific IgG antibodies in diagnostic use. In their study, the antibody test had a 98% sensitivity, correctly diagnosing 58 of 59 patients who had been diagnosed by standard methods. Specificity was 71%.
