CORONAVIRUS – Serology testing: FAQ

Frequently asked questions:

Why and when should I get tested for COVID-19 following vaccination?
Immunity develops in the first weeks after vaccination. Quantitative serological assays may allow to:
- Identify if a body’s immune response has been activated
- Monitor possible changes of the antibodies levels
We recommend to wait up to 2-3 weeks after receiving the second vaccine dose prior to undergoing serology testing.
When and why should I undergo serology testing if my PCR test is positive?
Serology testing will determine if you have developed an immune response against the virus. Serology tests should be performed about 3 weeks after the onset of symptoms.
There is currently no conclusive evidence that people who have recovered from COVID-19 and have antibodies are protected from a second infection.
Shall I get an antibody test although I have not been vaccinated or (obviously) infected?
Getting an antibody test may be helpful even if you haven’t been vaccinated or if there is no evidence that you have been infected with COVID-19. Antibody tests indicate if you have been infected with the virus in the past.
Serology testing may be significant in the following cases (especially when you haven’t regularly taken part in the large scale testing program):
- You may have previously developed mild symptoms
- You may have had an asymptomatic infection
- You may have regular contact to infected patients
Can the antibody test replace the vaccine passport?
No. Serology tests for SARS-CoV-2 are not the same as the actual vaccine passport but they allow a better understanding of how you have been affected by the virus.
What is the purpose of serology testing for COVID-19?
Serologic tests can identify individuals who have had contact with the virus and have developed an immune response against the SARS-CoV-2 virus (that causes COVID-19).
Note: serologic tests should not be used as the sole basis to diagnose an active infection.
The only method recommended for that purpose remains the PCR test (using a nasopharyngeal swab), which allows for detection of the SARS-CoV-2 genome.
Is a medical prescription required for serology testing?

A medical prescription is not required for the serologic tests.

Does the CNS reimburse the serologic test?

At this time, the serological test is still not reimbursed by the CNS.
