Hematology analyzers capable of performing complete blood count (CBC) have lagged in their prevalence at the point-of-care. Sight OLO (Sight Diagnostics, Israel) is a novel hematological platform which provides a 19-parameter, five-part differential CBC, and is designed to address the limitations in current point-of-care hematology analyzers using recent advances in artificial intelligence (AI) and computer vision. Accuracy, repeatability, and flagging capabilities of OLO were compared with the Sysmex XN-Series System (Sysmex, Japan). Matrix studies compared performance using venous, capillary and direct-from-fingerprick blood samples. Regression analysis shows strong concordance between OLO and the Sysmex XN, demonstrating that OLO performs with high accuracy for all CBC parameters. High repeatability and reproducibility were demonstrated for most of the testing parameters. The analytical performance of the OLO hematology analyzer was validated in a multicenter clinical laboratory setting, demonstrating its accuracy and comparability to clinical laboratory-based hematology analyzers. Furthermore, the study demonstrated the validity of CBC analysis of samples collected directly from fingerpricks.
能够进行全血细胞计数(CBC)的血液分析仪在即时检测中的普及程度一直滞后。Sight OLO(以色列Sight Diagnostics公司)是一种新型血液学平台,可提供19项参数的五分类全血细胞计数,并旨在利用人工智能(AI)和计算机视觉的最新进展解决当前即时检测血液分析仪的局限性。将OLO的准确性、重复性和标记能力与Sysmex XN系列系统(日本Sysmex公司)进行了比较。基质研究比较了使用静脉血、毛细血管血和直接采自指尖的血样的性能。回归分析显示OLO与Sysmex XN之间具有很强的一致性,表明OLO对所有全血细胞计数参数的检测都具有很高的准确性。大多数测试参数都显示出高重复性和再现性。OLO血液分析仪的分析性能在多中心临床实验室环境中得到了验证,证明了其与基于临床实验室的血液分析仪相比的准确性和可比性。此外,该研究还证明了直接从指尖采集的样本进行全血细胞计数分析的有效性。
