PCR (Polymerase Chain Reaction) vs Rapid Test

The rapid kit looks for antibodies in the blood produced in response to infection by coronavirus, whereas the RT-PCR looks for the virus itself (through RNA extraction) in respiratory specimens.

  1. The PCR Test has a higher sensitivity to detect COVID-19 compared to the Rapid Test. 
  2. PCR technique has an accuracy rate of 99%, whereas many Rapid Tests in the market has an accuracy of less than 80%.
  3.  It is advised all test to be conducted by a licensed phlebotomist, medical practitioner or professionals, conducted at medical centers or labs which have been prepared and verified to have met the stringent requirements set by MOH Malaysia.
  4. PCR Test if positive indicates you are infected by the virus; where as Rapid Test positive indicates you are exposed to the virus but not sure if the virus is still in your system, and negative does not indicate you are not infected by the virus.
  5. PCR Test takes 24-72 hours to produce a result, where as Rapid Test takes 2-15 minutes.

COVID-19 ANTIBODY TEST KIT (IGM/IGG) OR ‘DOT BLOT TEST’ HAS ITS DISADVANTAGES.

China Outbreak“The rapid kit looks for antibodies in the blood produced in response to infection by coronavirus, whereas the RT-PCR looks for the virus itself (through RNA extraction) in respiratory specimens.

Since the rapid test relies on the presence of a sufficient amount of antibodies in the blood, factors like timing of the test, previous infections, immune status of a person, cross-reaction with other antigens, can produce false results. “
