Laboratory monitoring during treatment of onychomycosis in pediatric patients: A survey of provider perspectives and practices.

Pediatric dermatology providers are very likely to confirm the diagnosis of onychomycosis prior to systemic treatment. Significant variability was found in pretreatment and treatment laboratory monitoring, reasons for laboratory monitoring or deferral of testing, and timing of testing among providers. Knowledge of current practice trends as well as provider perspectives may be useful in the future development of consensus guidelines.
