5 antigens combination to enhance SARS-CoV2 serological test performances

CoViDiag is a High-Resolution COVID-19 serological diagnostic device. Developed with the cutting-edge multiplex SirYus technology, it simultaneously detects and identifies 5 antibodies produced against the SARS-CoV-2 virus, offering very precise and reliable results, with exhaustive immune profiling.

CoViDiag is a High-Resolution COVID-19 serological diagnostic device. Developed with the cutting-edge multiplex SirYus technology, it simultaneously detects and identifies 5 antibodies produced against the SARS-CoV-2 virus, offering very precise and reliable results, with exhaustive immune profiling.

Perfectly automatable on several mainstream devices, CoViDiag is a very competitive technology, that enables to test and characterize several hundred samples a day.

Its precision can confirm positive or negative samples with a very high accuracy. CE marked and validated by the CNR (Pasteur Institute), Covidiag is compliant with french HAS (Haute Autorité de Santé) and regulatory demands.

Key points of CoViDiag

• High Performances : 99% specificity and 98,2% sensitivity*
• High Definition : 5 antigens tested in one test (anti-N, anti S1, anti-S1-RBD, anti-S2, anti-S1-NTD)
• Flexibility : Various isotypes detection 
• Simplicity : Same Protocol as an ELISA Test
• Adaptability : Standard lab equipment : Quick visual interpretation **

*Diagnostic sensitivity on plasma samples collected over 8 days after symptoms onset and infection confirmed by rt-PCR.
**Automated interpretation is available on a specific reader.
