雅培的检测方法与美国传染病大流行期间的标准检测方法原理不同。通常病人样本会被送到实验室,然后用一种叫做PCR的方法进行处理,这种方法能搜索微小的冠状病毒基因物质。为了使PCR起作用,样品必须反复加热至高温再冷却下来。雅培试验也寻找病毒基因物质,但它在一个温度下就能发挥作用。这就是为什么它的运行设备可以这么小...
一,抗体检测? 当然不是,这是妥妥的核酸检测试剂盒 二,为啥五分钟出结果?PCR没有这么快啊? 传统PCR的确没这么快,因为有变性,复性,延伸的三个步骤,这三个步骤所需要的温度不同,而酶对温度的要求又很高,所以在进行不同步骤时,其他步骤是没有进展的。 而这个仪器用到了恒温PCR技术中的NEAR技术(注意恒温PCR是一...
实际上,为了便于理解,各位完全可以将Alere i检测仪器类比于PCR扩增仪,其功能也类似。而测试盒则主要有三部分组成,但为了通俗易懂,焜哥并没有按照专利中的英文直接翻译过来,而是根据其具体功能来命名各个部分,如上图中所示的,中间蓝色管为样品管,其功能相当于前面提到的离心管A;黄色管为扩增管,相当于离心管B;白色...

Objective:We sought to evaluate the test characteristics of Abbott ID-Now as a screening tool compared to polymerase chain reaction (PCR) testing for identification of COVID in an asymptomatic emergency department population. Methods:We performed a prospective study enrolling a convenience sample of ...
Real-time PCR is suitable to be run as high-throughput approach which takes between 3 and 4 h for low numbers of specimens including RNA extraction, but can take up to more than a day for high numbers of specimens due to pre-analytical procedural steps. However, a well-appointed ...
Given the potential advantages of this device over more traditional format molecular tests such as real-time RT-PCR, a small evaluation of the ID NOW COVID-19 test was conducted at two laboratories to assess its performance. Residual positive and negative nasopharyngeal patient samples collected in...
We evaluated the analytical performance of ID NOW COVID-19 2.0 assay versus conventional real-time reverse transcription-polymerase chain reaction (RT-PCR) using a total of 792 clinical samples from nasopharyngeal and oropharyngeal swabs, stored in frozen universal transport medium samples. Positive per...
