  • Title: Enumeration of clue cells in rehydrated air-dried vaginal wet smears for the diagnosis of bacterial vaginosis.
    Author: Larsson PG, Platz-Christensen JJ.
    Journal: Obstet Gynecol; 1990 Oct; 76(4):727-30. PubMed ID: 2216211.
    Abstract:
    Among 235 women attending an outpatient clinic, the diagnosis of bacterial vaginosis was made using three of the following four criteria: typical discharge, pH more than 4.5, positive amine sniff test, and clue cells in a wet smear. These findings were correlated with the finding of clue cells in air-dried wet smears rehydrated more than 1 month after the visit. The rehydrated specimens had the same microscopic appearance as a nonpreserved wet smear. The demonstration of clue cells in the rehydrated smears correlated with the composite diagnosis of bacterial vaginosis with a sensitivity of 96% and specificity of 98%. In a busy multi-physician setting, the scoring of clue cells in stored and rehydrated smears can be used to obtain consistent readings for wet-smear diagnostics, thus simplifying teaching and increasing the utility of wet smears in clinical research.
