Also called serological test, this process takes lesser time than the RT-PCR 2021-02-01 2020-02-11 According to her, PCR testing is more complicated than other tests. Samples taken from patients have to be put into a transport medium so the virus can remain viable. After that, the virus is extracted and tested using the PCR method to see if Covid-19 is present. At Siloam, the testing is done using four PCR machines owned by MRIN.

2021-02-01 · For it was Christian Drosten who developed the PCR Corona test in January 2020, which from then on served as the standard method for detecting the Coronavirus SARS-CoV-2 worldwide. As Director of the Berlin Charité Institute, he is a very influential advisor to the German government and participated as an expert in many government press conferences. PCR test. Also called a molecular test, this COVID-19 test detects genetic material of the virus using a lab technique called polymerase chain reaction (PCR). A fluid sample is collected by inserting a long nasal swab (nasopharyngeal swab) into your nostril and taking fluid from the back of your nose or by using a shorter nasal swab (mid-turbinate swab) to get a sample.
