Some people may not be able to distinguish between the symptoms of the emerging corona virus 2019 and other respiratory diseases, and some individuals may be infected with the virus without symptoms, or without noticeable symptoms, so it is important to conduct a corona examination to diagnose the disease. To monitor the new Corona virus infections, many tests have been developed since the SARS-Cov 2 virus first appeared at the end of last year until today. About 350 types of detection techniqes are currently used in all laboratories of the world. They can be divided into three pivotal sections: the [PCR] examination, which is also known as the "polymerase chain reaction" examination, then the [antigen-tests] known as antibody tests, and finally the ELISA test. The aim of this descriptive minireview, generally, is to shed light on the main detection techniques used in Covid 19 diagnosis. |
