Clue cells are one of the routine leukorrhea tests that can be detected in bacterial vaginosis.
Clue cells are caused by the adhesion of most anaerobic bacteria, especially Gardnerella, to the squamous epithelial cells of the vagina, which can lead to changes in the normal epithelial cells, with irregular edges, roughness, and lack of transparency.
When a large number of clue cells appear in vaginal secretions, it generally suggests that the patient has bacterial vaginosis, so clue cells are common in the vaginal secretions of patients with bacterial vaginosis. It should be noted that sexual contact is prohibited 3 days before the examination, and the examination can be performed 3 to 7 days after menstruation.
When the presence of clue cells often suggests the presence of bacterial vaginosis, prompt medical attention should be sought.
