frequently asked questions
Why are antibodies important?
This protects us in two main ways. First, antibodies can bind to antigens on the outside of the pathogen to stop it from entering our cells. This is particularly important for viruses, which enter human cells to replicate (so if the virus is stopped from entering your cells, you won’t get sick).
Second, by binding to antigens on the pathogen, antibodies also signal other white blood cells known as phagocytic cells, which engulf and destroy the pathogen. So, in short, antibodies can both neutralise a virus and mark it for destruction.
What is a COVID antibody test and how does it work?
It's a test that measures the quantity of antibodies in your blood to various parts of the virus, allowing us to predict your degree of protection and how long it will likely last. The test starts with nurse taking a small sample of blood, usually from your arm, which is sent to a central laboratory to be put into the Attomarker instrument. This generates the highly accurate results and the key findings and predictions on protection.
How accurate is my test?
Will it tell me if my vaccine has worked?
How do I get a copy of my antibody results?
The results will be generated as a report, with graphs, explanations and guidance. These are emailed directly to you, along with how to access a greater level of explanation and guidance if you want to know even more. They are also available from the Biomark app.
Will the test tell me whether I have COVID-19 now?
No. It is not an antigen test or a PCR test replacement. If you think you have COVID-19 now, please follow NHS advice. This is not the right test at this moment if you suspect you already have Covid-19.
Does the test meet the standards laid down by the UK regulator?
The test carries a full CE Mark and registration with the MHRA, the UK national agency that regulates medical products and technology. It is fully approved.
How soon after the vaccine can I take an antibody test?
Who will administer the test?
There are a number of steps but they are broadly split into taking the small blood sample and the processing of this sample through the technology. A trained nurse at a local phlebotomy centre (clinic that takes blood) will take the blood sample. This will then be sent to the central laboratory to arrive the next day and they will process it immediately, using their trained laboratory technicians. Your results are generally available within 24-48 hours of attending for your blood sample.
