Epidemiologic research requires identification of Chlamydia trachomatis serovars and detection of mixed infection. Antibody-based serotyping is unworkable when specimens are urine or vaginal swabs. We developed a reverse dot blot (RDB) to screen for multiple serotypes in these specimens. RDB yielded the predicted results on all artificially mixed samples and on seven of eight clinically mixed samples.
