Clinical Significance

The complement fixation assay for chlamydial infection is a genus-specific test for antibodies recognizing antigenic determinants common to all chlamydiae. Although useful in the diagnosis of lymphorgranuloma venereum (lvg) and psittacosis, this assay is unsatisfactory for the diagnosis of chlamydial trachoma or pneumonia. In lgv and psittacosis, titers may not be increased in convalescent versus acute sera, since most patients have been infected for several weeks before the acute specimen is collected.
