Objective: To detect Bartonella henselae IgG antibody among healthy people in Changping, Beijing.
Methods: Using indirect enzyme linked immunosorbent assay (ELISA) and immunofluorescence antibody assay (IFA) to detect IgG antibody of Bartonella henselae among human beings.
Results: The sensitivity and specificity of ELISA were 70.6% and 91.6% respectively, with the positive predictive value of serological test as 82.2%, and the negative predictive value as 84.9%, based on results of IFA. The positive rate was 34.5% among 357 healthy people on indirect ELISA but was 35.6% among 239 people with IFA.
