Clinica Chimica Acta:色素试纸:一种排除蛛网膜下腔出血的快速试验

蛛网膜下腔出血(SAH)会出现25%的死亡率或导致长期护理。SAH需要计算机断层扫描(CT)立即诊断。对于不确定的CT扫描,可以在脑脊液(CSF) 进行血红素色素的检测。

蛛网膜下腔出血(SAH)会出现25%的死亡率或导致长期护理。SAH需要计算机断层扫描(CT)立即诊断。对于不确定的CT扫描,可以在脑脊液(CSF) 进行血红素色素的检测。参比法是分光光度法,但需要大量的CSF和特定的设备。有时,尿样条被用作血红素色素检测的替代方法。但是,该方法需要在SAH背景中进行验证。本研究的目的是比较Multistix®尿液试条对血红素色素的检测与参考分光光度法以及最终临床SAH诊断的性能。

研究人员收集了136例疑似蛛网膜下腔出血样本。用尿试纸和分光光度法检测了100个样品的血红素,并对其性能进行了比较。

与作为参考分光光度法检测血红素色素相比,尿液测试条显示了高灵敏度(0.97)。有趣的是,血红素色素的缺失与SAH的缺失完全相关。

研究结果表明,如果没有分光光度计,则阴性的Multistix®尿液检测试纸可结合临床数据帮助排除SAH诊断,或作为床边诊断测试。原始出处:
