A combined IgG and IgM antibody panel is available (refer to Chlamydia Antibody Panel, IgG & IgM by IFA (0065100)). Differentiate between Chlamydophila species (C. psittaci, C. pneumoniae). 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.
- Patient Preparation
- Collect
- Plain red or serum separator tube.
- Specimen Preparation
- Separate serum from cells ASAP or within 2 hours of collection. Transfer1 mL serum to an ARUP Standard Transport Tube. (Min: 0.15 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as acute or convalescent.
- Storage/Transport Temperature
- Refrigerated.
- Unacceptable Conditions
- Contaminated, hemolyzed, or hyperlipemic sera.
- Remarks
- Stability
- After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
< 1:64 C. pneumoniae IgG.
< 1:64 C. psittaci IgG.
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.
