Tests and diagnosis discussion for Bacterial vaginosis: A health care provider must examine the vagina for signs of BV (e.g., discharge) and perform laboratory tests on a sample of vaginal fluid to look for bacteria associated with BV. ¹

A healthcare worker can examine a sample of vaginal fluid under a microscope, either stained or in special lighting, to detect the presence of the organisms associated with BV. They can make a diagnosis based on the absence of lactobacilli, the presence of numerous "clue cells" (cells from the vaginal lining that are coated with BV organisms), a fishy odor, and decreased acidity or change in pH of vaginal fluid. ²
