#ExistInterpData>The Chlamydia antibody test contains both species- and genus-specific antigens, and serological cross-reactions may be seen in both acute and convalescent samples (less than 1:128). A C. pneumoniae-specific reaction will exhibit titers twofold or greater than titers observed with C. trachomatis or C. psittaci serology. Any IgG titer may indicate past exposure to that particular species. IgG titers in recently infected individuals are typically greater than or equal to 1:512.
The Chlamydia microimmunofluorescent assay slides utilize C. psittaci, C. pneumoniae, and nine serotypes of C. trachomatis. The LGV strains of C. trachomatis are not included in this assay.

||In adult populations, the prevalence of antibody titers indicative of exposure to the organism ranges from 50-78%.
