In India, where malaria is endemic, the prompt and accurate detection of infections is crucial for disease management and vector control. Our study aimed to evaluate the "iRBC" flag, a novel parameter developed for routine hematology analyzers, for its sensitivity and specificity in detecting () infections. We used residual blood samples from patients with suspected malaria and compared the iRBC flag results with microscopy, which serves as the gold standard. Additionally, we compared the results with rapid immuno-chromatographic tests (RDTs) commonly used in the field. Our study included 575 samples, of which 187 were positive for . The iRBC flag demonstrated a high sensitivity of 88.7% and 86.1% on the XN and XN-L hematology analyzers, respectively, and a clinical specificity of 100% on both analyzers. Furthermore, the scattergram derived from each positive dataset exhibited distinct patterns, which facilitated rapid confirmation by laboratory specialists. Notably, the iRBC flag remained effective even in the presence of interfering conditions. Overall, our results indicate that the iRBC flag is a reliable and rapid screening tool for identifying in routine blood testing. Our findings have significant implications for malaria detection and control in endemic regions like India.
在疟疾流行的印度,及时准确地检测感染对于疾病管理和病媒控制至关重要。我们的研究旨在评估“iRBC”标记,这是一种为常规血液分析仪开发的新参数,用于检测()感染的敏感性和特异性。我们使用了疑似疟疾患者的残留血样,并将iRBC标记结果与作为金标准的显微镜检查结果进行比较。此外,我们还将结果与该领域常用的快速免疫层析试验(RDT)进行了比较。我们的研究包括575个样本,其中187个样本呈()阳性。iRBC标记在XN和XN-L血液分析仪上分别显示出88.7%和86.1%的高敏感性,在两种分析仪上的临床特异性均为100%。此外,从每个阳性数据集得出的散点图呈现出不同的模式,便于实验室专家快速确认。值得注意的是,即使在存在干扰条件的情况下,iRBC标记仍然有效。总体而言,我们的结果表明,iRBC标记是在常规血液检测中识别()的可靠且快速的筛查工具。我们的研究结果对印度等流行地区的疟疾检测和控制具有重要意义。
