其他指甲疾病可能类似真菌感染。因此，甲真菌病的诊断需要评估临床和实验室特征。甲真菌病由四种不同类型组成，每种类型都需要不同的技术来获得指甲样本。氢氧化钾（KOH）制剂可用于确认是否存在真菌。然而，需要真菌培养来鉴定病原体的特定属和种。在临床表现提示存在指甲真菌感染，但KOH制备和培养阴性的情况下，可能有必要对指甲进行组织病理学分析。
Other nail diseases may mimic a fungal infection. Therefore the diagnosis of onychomycosis requires an assessment of both clinical and laboratory features. Onychomycosis is comprised of four distinct types, each of which requires a different technique to obtain a nail specimen. A potassium hydroxide (KOH) preparation may be used to confirm the presence of fungi. However, a fungal culture is required to identify the specific genus and species of the pathogen. It may be necessary to perform histopathologic analysis of the nail unit in cases in which the clinical appearance suggests the presence of a fungal nail infection, but the KOH preparation and culture are negative.
