Covid Antibody Test London

In clinic Covid antibody tests from £100
Available at two central London clinic locations

A Covid Antibody Test tells you if you have been exposed to Covid-19 in the recent past and if you have some level of immunity (antibodies) to coronavirus in your blood stream. We also now offer a covid antibody test that tells you your level of immunity before and after vaccination as well as specific antibody tests for Delta and Omicron variants.

​

The antibody test is a full blood test taken from your arm, not by finger-prick. The test does not take more than a few minutes to conduct. The sample is then immediately sent to our laboratory for analysis. Results are available within 2-3 workings days and sent to you by email with a doctor's explanation.

​

Our antibody testing options have been evaluated by Public Health England (PHE) as suitable for detecting the production of Covid-19 antibodies and CE marked.

​

When do Covid Antibodies levels develop and what does this test tell me?

Covid Antibody Response.jpg

You will see from the above graph produced by Roche Diagnostics that antibody levels can go up from anytime after the first week after infection.

​

IgM and IgG levels are both different type of antibody and hence go up and down after infection at different rates. The IgM level usually starts to subside within 3-5 weeks of infection but an IgG level can remain elevated for many months following infection.

​

The SPIKE protein antibody level allows us now to assess the immune response following vaccination and we are able to also track your antibody levels following the first dose of vaccine, second dose of vaccine and beyond this. We recommend not doing the SPIKE antibody level until at least 2 weeks after you have been vaccinated in order to get the best idea of how strong your antibody response has been to the vaccine. 

​

If you have any more specific questions on which antibody test is the right one for you please do not hesitate to call us on 0203 488 4415 or email care@one5.health and we will reply back to you with some guidance.
