About me

It's been over a year since COVID-19 made its way to every corner of the world. At the moment, there are two main types of COVID-19 Rapid Test Kit commonly used to detect infections. Diagnostic tests are done to confirm if you currently have the virus and antibody (serology) tests help to identify people who have previously been infected with the virus by looking for antibodies in their immune system.


Diagnostic tests (the sample is usually taken with a swab from the nose/mouth)

Diagnostic tests are the Antigen Test Kit and PCR Rapid Test Kit(Polymerase Chain Reaction) that look for active coronavirus infection in the mucous or saliva. ART tests look for the coating or proteins from the virus while PCR tests detect nucleic acid (RNA), the genetic material of the virus. RNA tests are very sensitive and can remain positive even after the person has gotten better and is no longer infectious.


Antibody tests (also known as serology tests – blood tests that look for antibodies in your blood)

Antibody Test Kits look for coronavirus antibodies in people who have been infected with the virus. Antibodies are proteins made by the immune system to fight infections. The timing and type of antibody test affects accuracy as it can take 1 – 3 weeks after infection for your body to develop enough antibodies to be detected in a test. Antibody tests are a good way to determine if you have had significant exposure to the virus in the past but should not be used to diagnose someone with an active infection, due to the delay in production of antibodies after exposure to the virus.
