MRL Diagnostics' Chlamydia pneumoniae Micro-immunofluorescent assay (MIF) is intended for the qualitative detection and semi-quantitation of human serum IgA antibodies to Chlamydia pneumoniae as an aid in the presumptive diagnosis of Chlamydia pneumoniae infections. When testing serial serum draws, the IgA product can be used to identify patient sero-conversion. Since either the presence of antibodies to IgM or the detection of a four-fold IgG titer increase is highly diagnostic and indicative of acute or recent infection, it is recommended that, in addition to the IgA determination, both IgG and IgM determinations be performed on all patients suspected of Chlamydia pneumoniae infection.

Each kit contains ten 12-well slides, with fixed spots of C. pneumoniae, C. trachomatis, C psittaci and egg yolk sac as control. IgA conjugate, positive and negative controls are provided.
