To ask Her Majesty's Government what use is being made of reverse transcription polymerase chain reaction tests to address the Covid-19 pandemic.
1 June 2020
Reverse transcription polymerase chain reaction (RT-PCR), is used in many laboratories to test patient samples for the COVID-19 virus.
RT-PCR is used for detecting certain viruses to help diagnose infection. It is being used throughout the United Kingdom to detect the COVID-19 virus. RT-PCR makes millions of copies of a virus’ genetic material and these can be detected on laboratory equipment. If this equipment detects a signal, it means the test is positive (virus detected). If the equipment does not detect a signal, it means the test is negative (no virus detected).
