Extraction: When a laboratory scientist receives the sample, they isolate (extract) genetic material from the rest of the material in the sample.

After collection, the swab is sealed in a tube and then sent to a laboratory. Either type of swab is sufficient for collecting material for the COVID-19 PCR test. There are different types of nose swabs, including nasal swabs that collect a sample immediately inside your nostrils and nasopharyngeal swabs that go further into the nasal cavity for collection. A swab is a soft tip on a long, flexible stick that goes into your nose.

Sample collection: A healthcare provider uses a swab to collect respiratory material found in your nose.

There are three key steps to the COVID-19 PCR test: Please check with your healthcare provider if you’re feeling unwell during the COVID-19 pandemic - even if you’ve been vaccinated. And not all symptomatic people develop all of the symptoms listed above. Not everyone with COVID-19 develops symptoms.

Shortness of breath or difficulty breathing.

Your healthcare provider may recommend testing for COVID-19 if you have any of the following symptoms: The PCR test has been the gold standard test for diagnosing COVID-19 since authorized for use in February 2020. Scientists use the PCR technology to amplify small amounts of RNA from specimens into deoxyribonucleic acid (DNA), which is replicated until SARS-CoV-2 is detectable if present.

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. The test could also detect fragments of the virus even after you are no longer infected.

The test detects the presence of a virus if you have the virus at the time of the test. It’s a test to detect genetic material from a specific organism, such as a virus.
