JCLA:如何检测可疑的嗜异抗体?

2019-07-12 Gladiator MedSci原创

在免疫分析中,嗜异抗体仍然是一个重要的干扰来源,但目前对D‐二聚体干扰的报道很少。临床中发现的D‐二聚体水平异常是否也由嗜异抗体引起,或涉及其他机制尚不清楚。在本文中,研究人员将通过两个不同的例子来详细说明这个问题。 研究人员检测两例D‐二聚体水平显著升高患者的血清,并采用不同方法进行比较、稀释和处理嗜异抗体阻滞剂。同时,为了排除干扰,重点研究了D‐二聚体假阳性的原因,并对相关文献进行了系统

免疫分析中,嗜异抗体仍然是一个重要的干扰来源,但目前对D‐二聚体干扰的报道很少。临床中发现的D‐二聚体水平异常是否也由嗜异抗体引起,或涉及其他机制尚不清楚。在本文中,研究人员将通过两个不同的例子来详细说明这个问题。

研究人员检测两例D‐二聚体水平显著升高患者的血清,并采用不同方法进行比较、稀释和处理嗜异抗体阻滞剂。同时,为了排除干扰,重点研究了D‐二聚体假阳性的原因,并对相关文献进行了系统的回顾。

发现用不同的测试方法检测的D二聚体值是正常的(0.490.15μg /毫升),添加嗜异抗体阻断剂降低。根据文献资料,有66.7%(4/6)的文献表明干扰是嗜异抗体。

研究表明,嗜异抗体对D‐二聚体检测的影响仍然是一个巨大的挑战。不同的测量仪器和方法在测量D‐二聚体时可能存在显著差异。结合仪器测量方法,结合嗜异抗体阻滞剂,结合临床表现和影像学资料,可以消除大部分干扰。
