We studied on clinical availability of determination of serum anti-Helicobacter pylori (HP) IgG antibody in diagnosis of HP infection compared with bacterial culture.The population of this study consisted of patients who underwent endoscopic examination in our hospital. Detection and quantification of HP were made by the culture of biopsy specimens taken from the antrum and the body of the stomach. And, simultaneously, serum anti-HP antibody (HP-Ab) was measured by ELISA.The levels of HP-Ab in culture positive patients, 40.6±33.7U, are significantly higher than that of culture negative patients, 10.6±9.1U. Sensitivity and specificity in diagnosis of HP infection using determination of serum HP-Ab were 96.2% and 60.0% respectively. Significant correlation was found between the levels of serum HP-Ab and the amounts of HP bacilli in the biopsy specimen taken from body of the stomach.
