title: Predictive value of the "clue cells" investigation and the amine volatilization test in vaginal infections caused by Gardnerella vaginalis.
abstract: Although still controversial, an etiologic role of Gardnerella vaginalis is imputed in vaginitis. Besides isolation of the organism by culture, two alternative diagnostic procedures have been claimed to be useful: the investigation of "clue cells" in clinical specimens and the amine volatilization test or fishy odor perception in genital secretions. Herein we report on the findings of the simultaneous use of G. vaginalis isolation, the clue cell test and amine volatilization perception in specimens from 1,263 consecutive female patients referred to our clinic. Our results show that the simultaneous use of both alternative tests is very useful as a screening procedure. A negative result of both tests predicts a negative culture result in 99% of the cases. However, a positive result of either or both should be considered as an indication to proceed to culture and not as diagnostic of infection.
