Elisa and Rapid Test for SARS-CoV 2 serology

Both evaluated by French National Reference Center and 2 University Hospitals, serological 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.

Our IgG Assay offers a quantitative approach of Ig levels.

Based on this cohort and compared with molecular method, results show a sensitivity and specificity of 100% for IgG.
