Which of the following is one of Amsel's Criteria for diagnosing Bacterial Vaginosis?

Amsel's Criteria for diagnosing Bacterial Vaginosis includes specific clinical findings that help differentiate it from other types of vaginal infections. The positive whiff test is a key component of this diagnostic criteria. In this test, a fishy odor is produced when potassium hydroxide is added to a sample of vaginal fluid, indicating the presence of amines released by certain bacteria associated with Bacterial Vaginosis.

This symptom is particularly compelling because the odor often becomes more pronounced after sexual intercourse or during menstruation, which can help clinicians identify the condition more reliably. The whiff test is a simple yet effective clinical tool that, when combined with other criteria, aids in the diagnosis of Bacterial Vaginosis, making it a critical element of Amsel's Criteria.
