Chlamydia pneumoniae, IgG and IgM

Clinical Use

Use

This test is intended for the qualitative detection and semi-quantitation of human serum IgM and IgG antibodies to Chlamydia pneumoniae. It aids in the diagnosis of community-acquired pneumonia caused by Chlamydia pneumoniae in individuals presenting with pneumonia.

Special Instructions

Not provided.

Limitations

Results of this test are labeled for investigational purposes only by the assay's manufacturer. The performance characteristics of this assay have not been established by the manufacturer. The result should not be used for the treatment or for diagnostic purposes without confirmation of the diagnosis by another medically established diagnostic product or procedure. The performance characteristics were determined by Labcorp. All results must be correlated with clinical history, epidemiological data and other clinical data. The performance of this assay has not been established for diagnosing non-pneumonia diseases associated with Chlamydia pneumoniae (e.g., bronchitis, sinusitis, otitis, coronary heart disease, asthma and multiple sclerosis). A negative result does not rule out a present acute infection. A positive result does not always indicate a present acute infection as antibodies can persist in some patients for several months or more.
