Elisa and Rapid Test for SARS-CoV 2 serology

Both evaluated by French National Reference Center and 2 University Hospitals, serology testing kits were developed on antigen based on Protein S.

Their performances were demonstrated on several cohorts of patients and all report their diagnostic effectiveness.

Efficient ELISA tests

In accordance with French HAS (High Health Authority) recommendations, Theradiag offers you to carry out IgG and IgM assays directed against SARS CoV-2.

These ELISA kits did not show cross-reactions with coronavirus usually encountered (OC43, C229E, NL63, HKU1) or with other respiratory pathogens such as Influenza A/B, Legionella Pneumophila, C.Pneumoniae, M.Pneumonia, Haemophilus influenzae.

The antigens used are developped and produced in France thanks to an academic partnership. The assays are then produced, assembled and dispatched from our production facility based in Paris area.

Our IgG Assay offers a quantitative approach of Ig levels.

Based on a cohort of 169 samples and compared with another ELISA assay, results show a sensitivity and specificity of 99% for IgG anti-S and anti-N.
