Bacterial Vaginosi - Diagnosis 

What Is Bacterial Vaginosis? 

Bacterial vaginosis is a form of vaginitis, of which there are other types, such as yeast infections and trichomoniasis. Vaginitis is a broad term used to cover specific symptoms--inflammation of  the vagina that causes itching, abnormal discharge and pain. A healthy vagina has just the right balance  of helpful and harmful bacteria (flora), but when something disrupts this delicate balance and the harmful bacteria take over, bacterial vaginosis can result. You can get bacterial vaginosis without sexual activity. However, women with new or multiple sexual partners seem to be more at risk for getting bacterial vaginosis, according to the Mayo Clinic, as do women who douche and use an intrauterine device (IUD) for birth control. 

How It's Diagnosed 

A doctor, usually  a gynecologist, can order a test for bacterial vaginosis. This is done by taking a  sample of the vaginal fluids and observing them under a microscope  for the presence of the  bacteria that cause it. According to the National Institute of Allergy & Infectious Diseases, other clues that bacterial vaginosis may be present are an absence of lactobacill (one of the healthy bacteria) or the presence of cells in the vaginal lining that are coated  with bacterial vaginosis germs. The vaginal discharge may also have a malodorous "fishy" scent and be different in color and amount than noted in a healthy vagina. 

Ensuring Accurate Diagnosis 

To make sure that your doctor can give you an accurate diagnosis, the National Women's Health Information Center (NWHIC) recommends that you schedule your appointment at a time when you're not menstruating. Avoid douching before your appointment and don't use deodorant sprays that might mask the scent of the discharge. It's also recommended that you avoid having sex or using tampons at least a day before your appointment.
