Methodology:Semi-quantitative Indirect Fluorescent Antibody
CPT Codes: 86631 x1
Test Includes:C. trachomatis, C. pneumoniae, C. psittaci
Turnaround Time:Specimens are sent to reference laboratory Mon-Sat; results are reported in 1-3 days.
Special Instructions:Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Label samples as acute or convalescent.
Compliance:

This test uses a manufacturer labeled Analyte Specific Reagent (ASR) as the reagent providing the specificity of the assay. The test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.

Interpretive

Reference Range:
C. trachomatis IgG titer Less than 1:64
C. pneumoniae IgG titer Less than 1:64
C. psittaci IgG titer Less than 1:64
The Chlamydia antibody test contains both species- and genusspecific 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 the 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 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.
