Nasopharyngeal and oropharyngeal swabs were collected and tested for influenza viruses using real-time reverse transcriptase polymerase chain reaction (RT–PCR).
Between late November to 28 January 2016, 192 cases of Zika virus infection were laboratory confirmed through reverse transcription polymerase chain reaction.
Additional tests include reverse transcriptase polymerase chain reaction (RT-PCR) to detect the hepatitis A virus RNA, and may require specialised laboratory facilities.
Out of the samples taken from the 30 symptomatic patients, 3 tested positive for Zika virus by reverse transcription polymerase chain reaction (RT-PCR).
A total of 17 samples tested positive for Zika virus – 15 were IgM positive and 2 were positive by reverse transcription polymerase chain reaction (RT-PCR).
The standard molecular assays currently used in mobile and other laboratories supporting the Ebola response include the reverse-transcriptase polymerase chain reaction, or RT-PCR test.
折射计用于测量光学媒介的折射率。 不同的化学品有不同的折射率。 在化学合成后常用折射计测定样品的折射率以确定它的纯度或者间接地审查化学合成是否成功 。WHO WHO
