(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

Remarks
  
Stability
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)  
Reference Interval
< 1:20 C. trachomatis IgM.
< 1:20 C. pneumoniae IgM.
< 1:20 C. psittaci IgM.  
Interpretive Data
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 utilizes C. psittaci, C. pneumoniae, and nine serotypes of C. trachomatis. It does not include the LGV strains of C. trachomatis.

Statement A: Analyte specific reagents (ASR) are used in many laboratory tests necessary for standard medical care and generally do not require U.S. Food and Drug Administration (FDA) approval or clearance. This test was developed and its performance characteristics determined by ARUP Laboratories. The U.S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use.
