Ortho Clinical Diagnostics’ IgG Covid-19 antibody test has completed evaluation with Public Health England (PHE).

The test is hoped to be deployed as part of back-to-work strategies and in serological surveys to understand infection rates and immune responses throughout the population. It offers 100% specificity and runs on Ortho’s high-throughput, fully automated analysers including its flagship VITROS XT 7600 Integrated System, the VITROS 3600 Immunodiagnostic System and the VITROS 5600 Integrated System.

The test was CE marked on 18 May. Ortho previously announced the CE marking of its total antibody test, which detects the IgA and IgM alongside the IgG Covid-19 antibodies. These appear earlier in the infection, and can help determine the onset of a patient’s immune response.

Ortho is now collaborating with the UK Department of Health and Social Care to assess how to deploy the tests throughout the country
