This swab uses PCR to look for SARS-CoV-2 genetic material. The timing of the swab in relation to symptoms or recent infection affects its meaning.

Understanding the test
Also called SARS-CoV-2 PCR
A clinician may request molecular testing when symptoms or exposure make SARS-CoV-2 a possibility. Record when symptoms started and whether you recently tested positive.
PCR looks for genetic material from SARS-CoV-2 in a respiratory specimen.
The date of exposure, symptoms or a previous positive test helps explain a result.
Before your sample
There is no fasting requirement. Give the dates of symptom onset, exposure and recent positive tests, and follow the collection team's nasal-swab instructions.
A trained professional takes a sample from the nose using the swab specified for this test. You may briefly feel discomfort or watery eyes.

Detection means that viral genetic material was found at the sampled site. A negative result relates to that sample and time and may need reassessment if the illness evolves.

Patient questions
PCR can remain positive after the acute illness. The result alone cannot determine infectiousness or how severe the illness is.
A Detected result means viral genetic material was present in the sample. It most often reflects a current infection, with or without symptoms, but it can also come from residual fragments after recovery. Your doctor reads it against when your symptoms began and the public-health guidance currently in force.
PCR can detect leftover viral material for up to 90 days. Reinfection is also possible. If new symptoms start during this period, an antigen test is generally preferred to another PCR. Tell your clinician the date of your previous positive test.
