Chlamydia Antibody Panel, IgG & IgM by IFA
Ordering Recommendation

Differentiate between Chlamydophila species (C. psittaci, C. pneumoniae). Differentiate early IgM response to infection from persistent low-level titer. Because of cross-reactivity, a C. pneumoniae-specific reaction will exhibit titers two-fold or greater than C. trachomatis or C. psittaci serology. Limited value in the diagnosis of most oculogenital (eg, eyes, genitalia) chlamydial infections.
