COVID-19 (SARS-CoV-2) IgG Antibody Test approved for use in the UK by the MHRA


Please note that the antibody tests were developed for use and have been validated on venous blood samples (blood taken from a vein by a medical professional. The test has not been validated for samples of blood taken from a fingerprick. This may affect the accuracy of the test. This is why we only offer the test when a medical professional takes your sample from the vein, as recommended by the manufacturer.  This can be done at home or in the clinic.

Antibody results in 6-24 hours from the laboratory receiving the sample.



Antibody tests look for evidence of the immune response to covid-19. The aim to answer the question: have I been exposed to COVID-19 and produced an immune response? You can read in more detail about the types of test here. If you want to see if you are carrying covid-19 now, you need to use an antigen test (PCR test)

We do not yet know if the antibodies are protective to make you immune and we do not yet know how long this immunity will last. 

Public Health England released guidelines on 11th May, 2020 detailing the flowchart describing return to work following a SARS Cov-2 test result.


Therefore, anyone wishing to follow the above PHE advice should also have an antigen test which can be booked here.

If a person is exposed to covid-19, their immune system will react in order to start clearing the virus. This involves producing antibodies to help clear the virus and evidence suggests most patients who recover from covid-19 produce them. There are different types of antibodies: IgG is the most common and it is the IgG to covid-19 that is detected by this test. 

We strive to offer the most accurate test. It is CE marked and approved for us in the UK by THE MHRA. The test is extremely accurate with a sensitivity of >97.5% and specificity of 100%. You can read more about these terms here.

Producing antibodies takes time: testing should be undertaken 14 days or more following symptom onset. 

You can read more about what your antibody result means here

Results should be used in conjunction with information available from clinical evaluation and other diagnostic procedures. It has been recognised that there can be delayed responses in immunocompromised patients.
