whiff test

A semi-humourous term applied to the test for GARDNERELLA VAGINALIS organisms. A drop of 10% potassium hydroxide is added to a drop of vaginal discharge on a microscope slide. If the test is positive a distinct fishy smell, from the production of amines, becomes apparent. The test is not completely specific but is quick and of practical value.

A positive whiff test (mixing vaginal secretions with a 10 percent KOH solution and noting a fishy smell) and a pH > 4.5 on the vaginal secretion lead to a fairly definitive diagnosis of bacterial vaginosis.
The four diagnostic elements are: A vaginal fluid of pH>4.5, presence of "clue cells" (Epithelial cells with unclear borders, dotted with bacteria) on microscopic examination of vaginal swab samples in normal saline, milky homogeneous, adherent vaginal discharge and a positive 'whiff test, which is accentuation of an amine or 'fishy' odor of discharge after addition of 10% potassium hydroxide.

Other laboratory signs include a vaginal pH greater than 4.5, a positive whiff test (fishy odor on addition of 10 percent KOH to vaginal secretions), and abnormal vaginal flora (absence of lactobacilli and increase of Gardnerella and anaerobes).
