UPDATE ! COVID-19: Biological parameters

COVID-19 – (SARS-CoV-2) – screening for S gene By RT-PCR

 From the 14th of June 2021, Eurofins Biomnis laboratory offers a screening test for the 3 significant mutations E484K, E484Q and L452R, to be performed in case of a positive test

The evolution of the distribution of the different strains of SARS-CoV-2 and the emergence of new variants of concern (VOC) or of interest (VOI) leads to the evolution of the targets of the screening tests

Screening for anti-S or anti-RBD antibodies (SARS-CoV-2 virus)

Humoral immunity developed from contact with the SARS-CoV-2 virus (post-disease) takes the form of production, by B lymphocytes, of antibodies targeted against the spike (S) and nucleocapsid (N) antigens of the virus: with the appearance of anti-N, anti-S and, more specifically, anti-S1 and anti-RBD type antibodies.

Thus, screening for anti-S or anti-RBD antibodies can be used to search for the presence of humoral immune markers after a Covid infection (or signal a previous contact if diagnosis could not be made), as they seem to persist for longer than anti-N antibodies.
Furthermore, anti-S or RBD antibodies can also be used post-vaccination.

From 1 April 2021, Eurofins Biomnis will be able to perform a “Screening for anti-S or anti-RBD antibodies”

  • Analysis code: SRBD
  • Sample:  Minimum 500 microlitres of serum
  • Transport temperature: refrigerated
  • Price: Contact the International Division
  • When requesting the test, please state: “Assay of anti-S or anti-RBD antibodies”

COVID 19 / Influenza virus A and B – panel – direct diagnosis – PCR

This testing allows the detection of two viruses : Influenza A/ B  and SARS-CoV-2   It is carried out by multiplex RT-PCR on a nasopharyngeal swab.

COVID-19 (SARS-CoV-2) – direct diagnosis – PCR

This analysis allows the diagnosis of COVID-19 (SARS-CoV-2) infection. It is based on the detection of SARS-CoV-2 RNA by a real-time RT-PCR technique, in particular via a nasopharyngeal swab.

COVID-19 (SARS-CoV-2) – serology total Ig

This analysis allows the diagnosis of COVID-19 (SARS-CoV-2) infection. Specifically, it is used to determine whether a person has produced antibodies in response to an infection with the virus.

The analysis is based on the detection and quantification of SARS-CoV-2 specific antibodies using a blood sample
