Tips On How To prepare Yourself Properly Before PCR Test?

A polymerase chain reaction (PCR) test is performed to detect genetic material from a specific organism, such as a virus. A PCR test for COVID-19 is a test used to diagnose people who are currently infected with SARS-CoV-2, which is the coronavirus that causes COVID-19. The PCR test is the “gold standard” test for diagnosing COVID-19 because it’s the most accurate and reliable test.

According to the Government of Ontario, the nasopharyngeal swab is the optimal sample collection method for COVID-19 testing.

Before doing the test, you should pay attention to the following steps.


  • Blow your nose and clean your nasal cavity. This step reduces the probability of the sample being contaminated.
  • If you have had recent nasal/oral/pharyngeal surgery, have an open wound in the nasopharyngeal area, are on anticoagulant medication or have a history of blood clotting-like disorders, and any complications that might during past nasopharyngeal swab collections, please inform the collection staff before collecting the nasopharyngeal swab.
  • Keep some tissues in hand. A sore and itchy nose may occur during the process, and if you sneeze, you can immediately cover it with a tissue or your elbow.
  • You should not smoke, drink alcohol or chew gum before sampling.
  • You need to wear the mask correctly, pull down the mask before the test to expose the nose, and wear it immediately after the test. A spare mask can be prepared to facilitate timely replacement.
  • Before and after PCR test, you need to pay attention to hand hygiene.
