Clinical Performance data
In 222 patients (at 11 centers) suspected of having tinea unguium on visual inspection, a sample was collected from a foot or hand nail according to the guidelines for diagnosis and treatment of cutaneous fungal infection. The sample was crushed into 3 pieces and subjected to measurement with this kit, direct microscopy and PCR (only samples for which the results of this kit and direct microscopy were inconsistent), respectively. Sample collection, direct microscopy, this kit and PCR were performed by different persons under blinded conditions.
Comparison between the results of Diafactory® Tinea Unguium and PCR incorporating direct microscopy Analyses were performed on 222 patients. In 5 patients in whom the results of this kit and direct microscopy were inconsistent and PCR could not be performed because the amount of sample was insufficient, the result of direct microscopy was used.
