AimHere, we evaluate the ddPCR platform using an evaluated qPCR-based diagnostic assay for the detection ofLeishmaniainfection in Cutaneous Leishmaniasis patients.MethodsA standard curve of culturedLeishmaniaparasite material and clinical samples of CL patients were tested with ddPCR to determine the analytical and diagnostic performance.ResultsThe limit of detection of the assay on the ddPCR platform was much higher than the published limit of detection of the same assay on the qPCR platform (100 vs 1 parasites/mL, respectively).ConclusionWhile the performance of this assay in ddPCR format was acceptable for research purposes, it is not sufficient for clinical diagnostic purposes. The assay is more suited to the qPCR platform.
