The most common infectious causes of vaginitis are bacterial vaginosis, vulvo- vaginal candidiasis and trichomoniasis. Health care providers traditionally diagnose vaginitis using a combination of clinical symptoms, examination findings, pH of vaginal discharge, microscopy and special tests like ‘Whiff’ or ‘sniff’ test.

Diagnosis starts from the review of the medical history of vaginal or sexually transmitted diseases, next is to perform a pelvic examination and using a speculum to look into the vagina and collect a sample for lab testing and for wet mount and pH testing. An elevated pH is an indication of BV or TV. But pH alone is not reliable.

Bacterial vaginosis (BV) is caused by gardnerella vaginalis is the most prevalent cause of vaginal discharge.

  • Positive whiff test (fishy odour or adding 10% potassium hydroxide solution to the vaginal discharge)
  • Atleast 20% of ‘clue cells’ (vaginal epithelial cells with borders observed by bacteria as wet mount preparation on a special stain named Gram’s stain’

 

In Trichomonias which is caused by protozoan presents with greenish yellow frothy discharge.

In vulvo-vaginal candidiasis caused by an yeast infection, presents with curdy white or cottage cheese like discharge and it can present with itchy, excoriations and swelling of the genital area.
