KOH test on a vaginal wet mount, showing slings of pseudohyphae of Candida albicans surrounded by round vaginal epithelial cells, conferring a diagnosis of candidal vulvovaginitis. The KOH test , also known as a potassium hydroxide preparation or KOH prep , is a quick, inexpensive fungal test to differentiate dermatophytes and Candida albicans ...
The basis for the diagnosis of kerion is clinical finding, positive microscopic examinations (such as positive KOH preparation, Lactophenol cotton blue wet mount, Chicago sky blue stained (CSB) slide, Calcofluor white stained slide, Periodic acid–Schiff stained slide, and Gomori’s methenamine silver stained slide), mycological culture and modern molecular tests (such as PCR-reverse line ...
The study saw that out of 150 patients CFW showed positive in 95 of them. The study also reviewed key advantages for using the Calcofluor-White stain over KOH. It discussed that CFW requires a quick screening time as it can be seen on low power objectives and can be done within a minute while KOH requires about 3–4 minutes for each slide.
About 112 g of KOH dissolve in 100 mL water at room temperature, which contrasts with 100 g/100 mL for NaOH. [14] Thus on a molar basis, KOH is slightly more soluble than NaOH. Lower molecular-weight alcohols such as methanol, ethanol, and propanols are also excellent solvents. They participate in an acid-base equilibrium.
Vaginal wet mount showing slings of pseudohyphae of Candida albicans surrounded by round vaginal epithelial cells, conferring a diagnosis of candidal vulvovaginitis.. A vaginal wet mount (or vaginal smear [1] or wet prep [2]) is a gynecologic test wherein a sample of vaginal discharge is observed by wet mount microscopy by placing the specimen on a glass slide and mixing with a salt solution.

A positive reaction of Schaeffer's test, which uses the reaction of aniline and nitric acid on the surface of the mushroom, is indicated by an orange to red color; it is characteristic of species in the section Flavescentes. The compounds responsible for the reaction were named schaefferal A and B to honor Schäffer. [3]
