About PCR test
What is a PCR test?
RT-PCR virological tests were only reserved for people with symptoms suggestive of Covid-19 contamination or contact subjects. Now, Covid-19 PCR tests have become widespread since last July. Thus, the number of PCR tests carried out is now clearly increasing (1 million tests are carried out each week).
This sample taken from the upper respiratory tract using a large cotton swab called a “swab” makes it possible to detect the presence of Covid-19. The test lasts a few seconds and several hours are necessary before obtaining the result.
However, this method is not only used to diagnose Covid-19. It can also be used for other viral diseases such as herpes, hepatitis A and E, HIV, dengue or whooping cough.
