Test done on 260 reoccuring cases
Finding : False positive result of corona test !
A team of South Korean researchers has revealed that reports of recovered coronavirus patients testing positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection a second time round are due to testing errors and not actually reinfection.
The conventional test used to detect SARS-CoV-2 is the polymerase chain reaction test or PCR test. However, there are technical limitations to the test. It cannot distinguish whether the virus in the patient is alive or dead.
“PCR testing that amplifies genetics of the virus is used in Korea to test COVID-19, and relapse cases are due to technical limits of the PCR testing. The respiratory epithelial cell has a half-life of up to three months, and RNA virus in the cell can be detected with PCR testing one to two months after the elimination of the cell .
