What diagnostic test is used for candidal balanitis?

Explanation:
Direct microscopy with a potassium hydroxide prep is used because it quickly reveals fungal elements by clearing background cells and debris. Candida balanitis typically shows budding yeast forms and pseudohyphae, which are characteristic and guide antifungal treatment right away. Gram stain can sometimes show yeasts, but it’s less sensitive for detecting Candida in penile samples and may miss cases. Urine culture isn’t relevant to a localized balanitis, and culture on blood agar, while it can grow Candida, isn’t the rapid, bedside diagnostic test used to confirm this presentation.
