Fact Check

What is a COVID-19 PCR test?

The polymerase chain reaction (PCR) test for COVID-19 is a molecular test that analyzes your upper respiratory specimen, looking for genetic material (ribonucleic acid or RNA) of SARS-CoV-2, the virus that causes COVID-19. It is the most commonly used and reliable test for diagnosis of COVID-19 performed using nasopharyngeal swabs or other upper respiratory tract specimens, including throat swab or, more recently, saliva. 

Can viruses other than Coronavirus cause a PCR test to give a false positive report of Covid?

No. PCR test is not used to detect all the microorganisms mentioned in the viral social media post.

The primer design is specific to the genome sequence of the SARS-CoV-2 virus and to make sure that the test does not react with other pathogens. RT-PCR tests are designed to specifically detect SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) RNA.
