Serological Tests: These help to identify if you had a previous infection with the virus.
If you think that you have been exposed to the virus or you are experiencing Covid-19 symptoms, you will receive these two types of diagnostic tests
In molecular tests, various techniques such as reverse transcription-polymerase chain reaction and isothermal amplification are used to identify the viral genetic material present in the test sample.
This is the newest form of test used for the detection of the virus. It is cheaper than molecular tests due to the simplicity of design. Antigen tests are usually considered rapid tests, and they are not widely available. Antigen tests look for the specific protection present on the surface of the virus.
Serological tests require a blood sample. These tests detect the antibodies that are produced by the body to fight the covid virus. These antibodies are present in the blood and tissue of anyone who has recovered from Covid-19.
