Identify past infection or vaccine response

IgG and IgM Blood Testing

We offer two antibody tests to identify past infection with SARS-CoV-2 (COVID-19) and/or response to SARS-CoV-2 vaccinations. The tests available are developed by Roche and VirTus (an Imperial College London spin-out).

Both tests detect antibodies developed in response to the vaccines in use in the UK as part of the NHS' vaccine program. They utilise the receptor binding domain (RBD) of Spike antigen, where as traditional antibody tests seek the nucleocapsid.

Venous sampling available at

Oxford, Ely, Crawley, London

Venous sampling requires a healthcare professional to draw the blood from a vein. Capillary sampling enables the use of a home-test kit, where you draw blood from a fingerprick.
The VirTus test provides a quantitative score for both IgG (long-term) and IgM (short-term) antibody levels, and interpretation as to whether levels are Very high, High, Med or Low. The Roche provides one score for overall antibody level, and no interpretation
