新型混合对照物简化了临床实验室的质控

By LabMedica International staff writers
Posted on 11 Apr 2014
两种新型的液态化学对照物设计目的是减少常规化验时需要单独运行的质控次数,从而简化质控,节省时间和金钱,同时保证高度准确的结果和诊断。

这两种新型对照物是朗道实验室公司(Antrim, North Ireland, UK)的Acusera Liquid Chemistry Premium和Liquid Chemistry Premium Plus,它们使实验室能够在一次检验中对多达100种分析物运行质控,同时不牺牲性能或准确性。提供多分析物的对照并不是新概念;然而,朗道的这两种最新款对照物是世界市场上迄今为止最全面的,独特地混合了蛋白质、脂质、免疫测定、心脏标记物、血液标记物、治疗药和常规化学分析物。

Premium Plus有高、中、低三个浓度等级,覆盖了宽广的临床范围,实验室无需另外购买昂贵的低水平或高水平对照物。Acusera Liquid Chemistry Premium Plus对照物含有100种分析物,而Acusera "Liquid Chemistry Premium"对照物有91种分析物,具有下列特征。高水平的CRP和其它关键蛋白质消除了多种对照物的需要,极大简化了质控。它们是经过标定的对照物,为各类分析仪提供关键决策点的具重要临床意义的数值。两种对照物都是液体,容易使用,避免了可能的重构差错,提高了实验室的效率。这两种对照物在-20 °C至-70 °C的保存条件下高度稳定,开瓶后在2–8 °C下的稳定期长达7天,减少了实验室的浪费。它们是用人类血清制成的,能完全反映病人样本的真实情况。

它们是真正的第三方对照物,能更好地保证实验室无偏、独立地评估分析性能,从而有助于生成高度准确的结果和诊断。

John Campbell博士说:“这两种经过标定的对照物将有利于医学实验室运行各种常规化验,让他们可以把全部或大部分质控合并于一件对照物。”朗道公司全球质控经理Steven Jordan说:“我公司是全球领先的质控品供应商,Acusera Liquid Chemistry Premium和Premium Plus的发布更进一步拔高了这一声誉。我们很高兴推动质控的进步,帮助实验室提高性能和生产率,同时保证高度准确的结果,改进对病人的诊断。”

对照物现已在英国、欧洲、中东、远东和非洲上市。朗道公司正在等待美国FDA和中国国家食品药品监督管理局的批准。
