COVID-19 TESTING

2 tests available
Molecular testing (PCR/NAAT) and Rapid antigen testing (RAT)

Clinique LeBlanc + Savaria, private medical clinics, now offer COVID-19 testing. Whatever the reason, if you or a member of your family must be tested for COVID-19, our personnel will provide you with a fast service, which meets your needs and respects public health standards. Performed by appointment only, the two types of tests currently used in our clinics are the molecular test (PCR/NAAT) and the rapid antigen test (RAT), both approved by Health Canada. Read the following information to determine which test is right for you and do not hesitate to contact us should you have any questions or to make an appointment.

What you need to know about COVID-19 testing

Molecular testing (PCR/NAAT)

Analysis

Sent to laboratory

Résultats du dépistage

– 72 hours
– Attestation sent by email

Travellers

Recommended for international travel

Prior to surgery

Accepted (test performed 24 to 48 hours prior to surgery)

How it works

Detects the RNA of the SARS-CoV-2 virus

Details

The most used and the most trusted
– Reference test (diagnosis and management of the disease)
– Nucleic Acid Amplification Test (NAAT) that detects the presence of the virus by amplifying viral genetic material to detectable levels (polymerase chain reaction “PCR”)

Sample

– With a swab, samples taken from the nose and/or throat
– By gargling

Best time to perform test

– Presence of symptoms for less than 7 days

Receipt for insurance purposes

Included

Rapid antigen testing (RAT)

Analysis

On site, at the clinic

Test results

– 15 to 30 minutes
– Attestation sent by email
– A positive RAT result must be confirmed by a second laboratory test (PCR/NAAT)*

Travellers

Accepted by a limited number of countries

Prior to surgery

Generally refused (test results not accurate enough)

How it works

Detects the presence of antigens on the surface of the SARS-CoV-2 virus

Details

– Test to detect suspected SARS-CoV-2 virus infection
– Performance is generally less effective than tests analyzed in laboratory

Sample

– With a swab, samples taken from the nose and/or throat

Best time to perform test

– 5-6 days following the start of symptoms
– Possibility of a false negative: negative test when the person is actually infected (often at beginning or end of infection)

* Rapid antigen testing (RAT) is recommended for asymptomatic individuals, i.e. without symptoms of COVID-19 (fever, cough, loss of smell, muscle pain, etc.). If there is a strong suspicion of SARS-CoV-2 virus infection, the rapid antigen test (RAT) is not recommended since in case of a positive result, it is mandatory to do a molecular test (PCR/NAAT) to confirm the diagnosis. In fact, a positive rapid antigen test (RAT) result is a “presumed positive” case, not confirmed as positive, until a molecular test (PCR/NAAT) attests to the positive result.

The accuracy of the COVID-19 tests

A positive result means you have COVID-19. A negative result usually means you are not infected with COVID-19. The accuracy of the diagnosis may vary depending on when your sample is taken during your illness. For example, if you get tested too early as a result of your exposure to COVID-19, the amount of virus in your body may not be enough to generate an accurate result. If this is the case at the time of your screening, your test result could be negative and yet you would be infected. This type of result is considered a “false negative”.

The healthcare professionals base their diagnosis on the results of the test, as well as other factors, such as:

  • the symptoms;
  • the exposure;
  • the moment the test is performed.

In certain situations, the doctor may request another test or give a COVID-19 diagnosis even with a negative result.

Maintain sanitary measures, even if the test is negative

Approximately 15 to 30% of people with COVID-19 are asymptomatic and can still transmit the virus. In case of persistent doubt about a negative result, it may be advisable to repeat the screening test 24 to 48 hours after a first negative test. In addition, despite a negative result, one can be a carrier of the virus and become contagious the day after the test is conducted. It is for this reason that all sanitary measures must be maintained even in the presence of a negative result.

In case of travel, choose the type of test according to the country you are visiting

Consult the IATA site for details regarding approved tests in the country you plan on visiting. Several countries do not accept rapid antigen tests (RAT). Do not forget to also consider the requirements of the countries where you will have a stopover. It is your responsibility to verify and schedule the appointment for your COVID-19 test in a way that complies with the regulations of each country.

For surgery, perform a molecular test (PCR/NAAT)

To date, only molecular tests (PCR/NAAT) are accepted prior to a surgery. Since you must be tested for COVID-19 between 24 to 48 hours before your surgery, it is your responsibility to schedule the appointment for your test accordingly.<
