A modification of the test in which the antigen slides were pre-treated with a monoclonal antibody to chlamydial lipopolysaccharide, improved its ability to differentiate infections with C. trachomatis from those with C. psittaci or C. pneumoniae. %U https://www.microbiologyresearch.org/content/journal/jmm/10.1099/00222615-35-4-244
