ARCH PATHOL LAB MED:实验室医学中标本错误识别的分子监测?

2018-11-15 MedSci MedSci原创

标本错误识别是实验室医学中最重要的错误,仅在美国就可能导致数亿美元的额外医疗费用并增加患者人群的发病率。目前,已经有新技术可以明确记录标本的错误识别或污染; 然而,这项技术的价值目前取决于病理学家或其他医护人员对样本完整性的怀疑。本研究的目的是为了验证在提交用于常规手术病理检查的病例中存在可检测的未预期组织标本错误识别发生率的假设。 为了检验这一假设,研究人员选择了在不同时间和/或不同医院从

标本错误识别是实验室医学中最重要的错误,仅在美国就可能导致数亿美元的额外医疗费用并增加患者人群的发病率。目前,已经有新技术可以明确记录标本的错误识别或污染; 然而,这项技术的价值目前取决于病理学家或其他医护人员对样本完整性的怀疑。本研究的目的是为了验证在提交用于常规手术病理检查的病例中存在可检测的未预期组织标本错误识别发生率的假设。

为了检验这一假设,研究人员选择了在不同时间和/或不同医院从同一患者获得的标本,并使用通常用于法医人类DNA比较的标准化微卫星标记比较其基因型,以便识别之间未预料到的不匹配。标本配对作为“分子审核”的试验。优先选择肠道,前列腺和皮肤活组织检查,因为这些类型的标本具有错误识别可能性最大。

结果显示,在972个样本对中,1个样本显示出意想不到的不一致基因型谱,表明2个样本中有1个被错误识别。到目前为止,我们无法确定不一致的病因。

这些结果表明,实际上,即使在遵守严格的质量保证实践的环境中,也存在低水平的不可预测的组织标本错误识别。这项研究表明,随机,常规活检标本的分子审计可以识别隐匿的错误识别标本,并可能作为一个有用的质量指标。

不合格标本对检验结果的影响

临床检验工作中遇到的不合格标本主要表现在溶血、凝血、污染、采集量不足或过多、标识错误等。不合格标本产生的原因主要包括:(1)使用了错误的容器或添加剂;(2)使用了不恰当的采血器具,如使用规格过小或过大的针头容器,使用过大的负压真空管等;(3)样本标识错误;(4)标本采集过程中的操作不规范使标本发生溶血;(5)采血量过少或过多;(6)标本污染。不合格标本肯定会影响检验结果。

EGFR-TKI耐药后的检测标本选择:组织活检vs.液体活检

奥希替尼是一种不可逆的三代EGFR-TKI,可以选择性地抑制EGFR敏感突变和T790M耐药突变。2017年3月,奥希替尼在华上市,开创了EGFR TKI耐药后T790M阳性患者的精准治疗新时代。随着泰瑞沙的上市,如何敏感、准确地检测T790M突变成为临床关注的热点。

标本溶血真的会影响凝血结果吗?

标本溶血会使钾离子和一些酶等,从红细胞中释放出来,造成这些结果假性升高。因此,标本溶血对生化检验的影响是有定论的。

护士亲们,谢谢你给检验提供准确的标本

检验结果是临床医师在诊疗过程中所需要的重要信息,临床医师可以根据这些检验结果及病人的临床情况来区分疾病的不同阶段,观察疾病的变化,判断预后或观察疗效。所以分析前阶段样本的质量保证是直接关系到检验结果能否真实客观地反应患者当前病情的一个重要环节。
