Microscopic view of cultured<unk>  fungus When visiting a doctor, the basic diagnosis procedure applies. This includes checking the patient's medical history and medical record for risk factors, a medical interview during which the doctor asks questions (such as about itching and scratching), and a physical examination.<unk>  can usually be diagnosed by visual inspection of the skin and by identifying less obvious symptoms such as itching of the affected area. If the diagnosis is uncertain, direct microscopy of a potassium hydroxide preparation of a skin scraping (known as a KOH test) can confirm the diagnosis of<unk>  and help rule out other possible causes, such as candidiasis, pitted keratolysis, erythrasma, contact dermatitis, eczema, or psoriasis. Dermatophytes known to cause<unk>  will demonstrate multiple septate branching hyphae on microscopy. A Wood's lamp (black light), although useful in diagnosing fungal infections of the scalp (tinea capitis), is not usually helpful in diagnosing<unk> , since the common dermatophytes that cause this disease do not fluoresce under ultraviolet light.
