Here, we evaluate the ddPCR platform using an evaluated qPCR-based diagnostic assay for the detection of Leishmania infection in Cutaneous Leishmaniasis patients.
A standard curve of cultured Leishmania parasite material and clinical samples of CL patients were tested with ddPCR to determine the analytical and diagnostic performance.
The 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).
While 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.
本研究采用经过评估的基于 qPCR 的诊断检测方法评估 ddPCR 平台,用于检测皮肤利什曼病患者的利什曼原虫感染。
采用 ddPCR 检测培养的利什曼原虫材料的标准曲线和皮肤利什曼病患者的临床样本,以确定分析和诊断性能。
与 qPCR 平台上相同检测方法的已公布检测限相比,该检测方法在 ddPCR 平台上的检测限高得多(分别为 100 与 1 个寄生虫/ml)。
虽然该检测方法在 ddPCR 格式下的性能可满足研究目的,但不适用于临床诊断目的。该检测方法更适合 qPCR 平台。
