The detection of antibodies directed against SARS-CoV-2 has been available since the 4th of May 2020.
Serological tests allow for proper identification of people who mounted an immune response against the SARS-CoV-2 virus (regardless of whether they were symptomatic). Serology tests are blood-based tests and the determination of antibodies is performed in blood samples (serum).
Antibody detection tests: IgM and / or IgG production is only detectable on average within the second week after symptom onset in symptomatic patients.
We would like to point out, that at the current stage:
These applications and recommendations will be regularly updated according to the rapidly evolving knowledge on COVID-19 and to the governmental recommendations.
Serology tests and PCR-based tests cannot supersede each other, but rather effectively complement each other in the current epidemic situation.
RT-qPCR testing is especially useful for early detection of the disease and it will help prevent drawing wrong conclusions from a negative serology, which may have been performed too early (that is, before the immune shift). Serological tests help document the emergence of adaptive immunity and reach retroactive diagnosis.
Prescription: A medical prescription and a blood sample (1 tube) are required for the serology tests.
CNS medical acts (nomenclature): There is no detailed information available in this respect. We will get back to you at the earliest opportunity once we have received more information.
PCR testing should be conducted to detect the presence of the virus in patients. It will only be carried out by a medical prescription using a nasopharyngeal or an oropharyngeal swab (when collection of a nasopharyngeal specimen is not possible).
The sample quality has a direct impact on the quality of the test results. The swab sample should be collected by a healthcare professional trained on sampling methods in use.
