超高的MRD检测灵敏度
微小残留病 (Minimal Residual Disease, MRD) 是指白血病/淋巴瘤/骨髓瘤患者经治疗缓解后，体内仍残留少量癌细胞的状态，最终可能会引起疾病复发。因残留的癌细胞数量较少，不易察觉，因此需要更准确和灵敏地方法才能检测得到。
Seq-MRD®是基于二代高通量测序技术，通过对患者进行T细胞受体（TCR）或B细胞受体（BCR）高通量测序，从而高准确和高灵敏地对白血病/淋巴瘤/骨髓瘤患者体内微小残留病（MRD）进行检测服务的产品。能帮助临床医生预测长期疗效、评估治疗效果、监测缓解状态以及检测早期复发。
利用二代测序技术检测MRD的重要性
围绕微小残留病（MRD）检测的争议之一是其评估的最佳技术。 纽约纪念斯隆凯特琳癌症中心的Landgren教授在美国血液学会（ASH）2017年年会中接受采访，就MRD评估的最佳方法提出了他的看法。 强调了二代测序检测MRD的很多优势，比如可重复性和灵敏度均高于传统检测方法等。
相比传统的MRD检测方法，Seq-MRD®检测仅需五分之一的样本量便可达到100倍的灵敏度。Seq-MRD®能在100万个健康细胞中检测出隐藏的一个癌细胞。传统MRD检测一般用骨髓样本，但因这种检测技术灵敏度受限，无法在肿瘤负荷较低的血液样中检测到MRD，而Seq-MRD®检测使用骨髓和外周血样本均可，使用血液样本可以达到无创检测。
Seq-MRD®的优势
使用Seq-MRD®作为您MRD监控手段
二代测序方法作为新兴的MRD检测方法，也已受到国内外专家认可并推荐。2017年版国际临床实践指南（NCCN）、2016年版《中国成人急性淋巴细胞白血病诊断与治疗指南》和2017年版《中国多发性骨髓瘤诊治指南》均推荐高通量测序（NGS）作为MRD检测方法。
