Molecular / PCR Testing Process

Molecular tests detect genetic material – the RNA – of the coronavirus and are sensitive enough to need only a very tiny amount of it. The sample is collected with a nasal or throat swab and they tend to take hours to provide results. Molecular COVID-19 tests are designed to detect an active infection with SARS-CoV-2, the coronavirus that causes COVID-19. The most well-known molecular test uses a laboratory method known as reverse transcription polymerase chain reaction (RT-PCR) that is often called PCR. PCR and molecular tests work by looking for the virus’s genetic material in your test sample, which is usually taken by swabbing your nose or throat. Molecular tests analyzed by a laboratory are generally considered to be the most accurate method of diagnosing COVID-19.

Specimen

Nasopharyngeal / Oropharyngeal Swab

What the test will look for

Nucleic acids ie. RNA of Covid-19 Virus

Laboratory Testing

Molecular / PCR Testing of Covid-19 in Lab

Nasal samples are collected and tested for antigens, which are found in the SARS-CoV-2 virus. It can be even performed outside the conventional laboratory setting. This test is used to quickly obtain a diagnostic result.
This test is a rapid chromatographic immunoassay for the qualitative detection of specific antigens to SARS-CoV-2 present in the human nasopharynx. It provides only an initial screening test result. More specific alternative diagnosis methods should be performed in order to obtain the confirmation of SARS-CoV-2 an infection like COVID 19 PCR.

When Should I get Molecular test?

For diagnosis, an antigen test is most often used when PCR tests are not readily available. In these situations, a positive antigen test can be used to diagnose COVID-19 if your symptoms are strongly indicative of the disease.
Because there are many different applications of molecular COVID-19 tests, your doctor can best explain whether this kind of testing is appropriate in your situation. It is also important to note that who should get tested with a PCR or other molecular test can depend on available testing capacity in your area. When resources for testing are limited, certain uses of testing may be prioritized.

Frequently Asked Questions

The frequently asked questions (FAQs) on this page are for a general public or consumer audience.
A positive test result means that you most likely have COVID-19 now and should self-isolate: stay home, separate yourself from others, and take precautions to reduce the risk of spreading the virus, including using a face covering and practicing good hand hygiene and physical distancing. If your symptoms get worse, you should contact your local health care provider by phone.
