Overview
The diagnosis of Candida vulvovaginitis is based on the clinical findings, supported by laboratory findings. Laboratory studies done for diagnosis include measurement of the vaginal pH, visualization of hyphae on wet mount/ microscopy, as well as culture.
Laboratory Findings
The laboratory findings consistent with the diagnosis of Candida vulvovaginitis include:[1][2][3]
- Vaginal pH: vaginal pH is normal (ranges from 4.0-4.5)
- Wet mount or Saline preparation: It will help in detection of hyphae, clue cells and motile trichomonas differentiating different causes of vaginitis.
- 10% Potassium hydroxide preparation: It is more sensitive than wet mount to demonstrate budding blastospores or pseudohyphae.
- Culture: Culture for diagnosing candida vulvovaginitis not recommended in patients with positive microscopy. However, it should be done in a symptomatic woman with a negative microscopy and a normal vaginal pH. Culture using Sabouraud agar, Nickerson’s medium, or Microstix-Candida medium identify candida species with equal sensitivity.
Approach to patient with Candida Vulvovaginitis
The following is a algorithm for diagnosis and treatment of vulvovaginal candidiasis :
Symptomatic Vaginitis | |||||||||||||||||||||||||||||||
Whitish discharge adherent to the vaginal walls, excoriations and fissures in the genital area | |||||||||||||||||||||||||||||||
Perform direct microscopy of the vaginal discharge with saline or 10% KOH Estimate pH of vaginal discharge | |||||||||||||||||||||||||||||||
Negative direct microscopy pH < 4.5 | Positive direct microscopy | ||||||||||||||||||||||||||||||
Send for culture Consider azole therapy | No culture necessary | ||||||||||||||||||||||||||||||
pH < 4.5 No excess WBC's | pH > 4.5 Excess WBC's | ||||||||||||||||||||||||||||||
Start azole therapy | Consider mixed infection | ||||||||||||||||||||||||||||||
