Test Overview

Tests for bacterial vaginosis take samples of fluid from the vagina (Figure 1). The samples are looked at under a microscope to see if they show signs of infection.

Bacterial vaginosis can happen when certain types of bacteria that are normally in the vagina overgrow. It doesn't always cause symptoms. But the most common symptom is an increase in vaginal discharge. The discharge often has a fishy odour.

Tests

Tests for bacterial vaginosis include:

• Wet mount. A sample of vaginal discharge is checked for bacteria, white blood cells, and unusual cells called clue cells. If clue cells are found, it means you may have bacterial vaginosis.
• Whiff test. A sample of discharge is checked to see if a strong fishy odour is created when a special solution is added. A fishy odour usually means you have bacterial vaginosis.
• Vaginal pH. The pH of a sample of vaginal discharge is measured. Bacterial vaginosis often causes a pH that is higher than normal.
• DNA test. A sample of vaginal discharge is tested for the genetic material, or DNA, of this bacteria.

The vagina is part of the female reproductive tract. It extends from the uterus to outside the body. The opening to the vagina is located between the bowel opening (anus) and the opening for the bladder (urethra).
