Testing is the way many believe we will get to grips with Covid-19 and the government is making big decisions based on the data they produce. But how accurate are the tests? Subscribe to our channel

Testing for coronavirus is critical to our understanding of how widely the virus has spread and the data informs decisions on whether to tighten or ease lockdown measures. But are the tests for coronavirus fit for purpose?
Concerns have been raised about the tests’ accuracy. Some clinicians are worried that the tests are over-sensitive and could be picking up on the presence of virus fragments which are old or not actually infectious.
Health Correspondent Deb Cohen reports.

What is Coronavirus? Coronaviruses are a group of viruses that cause diseases in mammals and birds. In humans, coronaviruses cause respiratory tract infections that are typically mild, such as the common cold, though rarer forms such as SARS, MERS, and COVID-19 can be
lethal. Symptoms vary in other species: in chickens, they cause an upper respiratory tract disease, while in cows and pigs they cause diarrhea. There are yet to be vaccines or antiviral drugs to prevent or treat human coronavirus infections.
Who are BBC News? What is PCR Test? RT-PCR tests to detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA are the operational gold standard for detecting COVID-19 disease in clinical practice. Reverse transcription polymerase chain reaction (RT-PCR) is a laboratory
technique combining reverse transcription of RNA into DNA (in this context called complementary DNA or cDNA) and amplification of specific DNA targets using polymerase chain reaction (PCR).It is primarily used to measure the amount of a specific RNA. This is achieved by monitoring the amplification reaction using fluorescence, a technique called real-time PCR or quantitative PCR (qPCR). Combined RT-PCR and qPCR are routinely used for analysis of gene expression and quantification of viral RNA in research and clinical settings.
