The Spectrum Health Laboratory is no longer performing the Chlamydia Antibody Screen test (#8874). The reagent the Laboratory was using for this test is no longer available.
Specimens for Chlamydia antibody testing will now need to be sent to Mayo Medical Laboratories for their Chlamydia Serology panel (#37). This panel includes IgG and IgM antibodies to Chlamydia pneumoniae, Chlamydia trachomatis, and Chlamydia psittaci.
It should be noted that cross reactivity commonly occurs between these different Chlamydia species, especially for IgM antibodies. Infection by a particular organism generally yields IgG titers higher than those for non-infecting organisms.
Any questions concerning these changes may be directed to Sue Koekkoek, Medical Technologist in the Immunochemistry Department or to Dr. Richard Horvitz in the Pathology Department.
