• The PCR COVID-19 swab test is the most accurate,
  reliable test for diagnosing COVID-19. These
  tests are used to directly screen for the
  presence of viral RNA, which will be detachable
  in the body before antibodies form or the
  symptoms of the disease are present. You can have
  a PCR COVID-19 swab test same-day done at Claret
  Diagnostics.

What is PCR testing?

• During PCR testing, elements known as reverse
  transcriptase or DNA polymerase are added to a
  nasopharyngeal sample in the lab. These elements
  work to make various copies of any viral RNA that
  may be presentthese numerous copies of RNA help
  signal a positive result.

 How does a COVID-19 PCR test works?

• Sample collection is done using a swab to collect
  respiratory substance detected in the nose. A
  swab includes a long soft tip on a long, flexible
  stick inserted into the nose. 
• After receiving the swab sample, the laboratory
  expert performs a process called extraction,
  which isolates genetic material from the sample,
  including genetic material from any virus that
  may be present. 
• After the extraction process, experts use special
  chemicals and a PCR machine, called a thermal
  cycler. It causes a reaction that creates
  millions of copies of a small portion of the
  SARS-CoV-2 virus's genetic material.
