COVID-19 Antibody Test, COVID-19 Immune Response Test

Serological test for COVID-19

This blood test checks for the presence of antibodies resulting from past or recent exposure to COVID-19. To date, the scientific community still knows very little about immunity to COVID-19 and there is currently no test to ensure that the presence of antibodies confers protective immunity. This is not a screening test for active infection with COVID-19.

Take this test at Biron if you :

  • have been diagnosed with COVID-19 for at least 14 days;
  • suspect that you have been exposed to the virus, without a diagnosis of infection;
  • are wondering if you have been infected with COVID-19 at any time.

So you can:

  • confirm that you have been exposed to COVID-19 at some point;
  • be possibly warned if science ever confirms that the presence of antibodies confers protective immunity.

Specimen Type: Blood draw

A positive result: indicates that anti-SARS-CoV-2 antibodies were detected. This result suggests recent or past COVID-19 infection. The presence of antibodies to SARS-CoV-2 is not indicative of protection against SARS-CoV-2 infection.

A negative result: indicates that anti-SARS-CoV-2 antibodies were not detected in your sample. A negative result does not rule out SARS-CoV-2 infection and may be due to sampling too soon after infection or in an immunosuppressed patient.

Term of the Week

Hot zone

A hot zone is a section of a facility (sometimes an entire facility or even a city district) where there is a high risk of contamination by patients with an infectious disease. All individuals entering a hot zone must respect appropriate protective measures. By analogy, “cold zone” and “warm zone” are used to refer to areas where there is no infected individual or only individuals suspected of having an infection.
