About the Covid-19 Antibody Immunity Test & Testing Process
About the test
The Attomarker COVID-19 Antibody Immunity Test is unique. It is the ONLY test currently available that analysis and quantifies the antibodies you have developed, from infection or vaccination, towards the COVID-19 virus (SARS-COV-2) AND indicates whether they are likely sufficient to provide protection against infection AND how long your protection is likely to last. That’s an unprecedented level of insight into your immune system and how well protected you are against the virus.
Benefits of the test
- Know that your vaccine has worked and you have protective antibodies
- Discover how much your immunity has waned
- Find out whether you are at or below the ‘Edge of Immunity’ and thus risking being more vulnerable
- See if a Covid-19 infection has provided natural protection or not
- Use the information to better plan and time any boosters
- If you are a more vulnerable individual, it’s more vital you understand your degree of protection
About the test and it's accuracy
Let’s start with information about the Covid-19 Antibody Immunity Test itself.
The simple explanation is that a tiny venous blood sample is taken by a trained nurse at a phlebotomy centre (clinic that takes blood samples) and this is analysed in an Attomarker Liscar 6 Analyser, providing an accurate quantification of your various different antibodies to Covid-19 and its variants. Additionally, the results profile tells you whether you are above, at, near or below the Edge of Immunity, a term used to denote whether you are likely to be on the edge of protection from the SARS-COV-2 virus. Lastly, perhaps more importantly, it tells you how long your immunity is likely to last, allowing you to take additional protective measures to ensure you are not vulnerable.
The more complex explanation is that the technology, developed by award-winning research scientists at Exeter University, UK, is based on something called nanophotonic particles. These are highly sensitive, gold-based particles that analyse light profiles from the various components in the blood sample to produce a very accurate assessment of the quantities of various antibodies to Covid-19.
Test accuracy is measured by scientists in two ways. Sensitivity is how likely the test is to detect a positive result. Specificity shows how specific the antibodies are to COVID-19 and thus how trustworthy a negative result is. Attomarker’s Triple Antibody Test achieves 95% sensitivity and 96% specificity.

Understanding antibodies and immunity
Let’s explore a quick overview of antibodies and their role in protecting us from diseases i.e. immunity.
There are 5 types of antibodies all involved in different parts of the immune response, all starting with Ig. They all do different things and together make up our immune response.
- IgM is made quickly at the beginning of an infection as a first responder. It is not a great antibody, but the speed of response is helpful.
- IgA is found in the nasal fluids (mucosa) and may have a very important role in the COVID-19 infection, preventing the virus getting into the cells. There is also some information that IgA can get inside the cells to stop virus particles from being made.
- IgD is the least well-understood of the antibodies and needs more research.
- IgE is the antibody responsible for part of our allergy responses such as to food or hay-fever.
- IgG is the made during the acquired immunity response, either following a natural infection or stimulated by the vaccines. IgG is what is produced when you have a vaccine or a booster for COVID-19.
IgG antibodies stimulated by the COVID-19 vaccine, are Y shaped and work by one end sticking and hanging on to a very specific part of the COVID-19 virus. The other end of the antibody – the bottom of the Y, enables white blood cells to bind to the Y and start engulfing the antibody and the virus, neutralising it.
You might inhale say a billion virus particles per 1 Sq. mm of nasal passage surface. The Attomarker test uses a blood antibody threshold or level of 3.4 mg/L of blood, which equates to roughly 100 billion antibodies in your nasal mucosa. This should provide protection against infection and also ensure that any virus particles sneezed back out of the nose continue to be covered, meaning the antibodies could also help prevent transmission too.
It is analysing whether you have enough IgG antibodies that allows the Attomarker COVID-19 Antibody Immunity Test to analyse whether you are likely to have sufficient protection to avoid infection and/ or recover easily without severe illness. We use the data to tell just how long you are like to remain protected, vital information for managing your personal health security.

Important Points About the Covid-19 Antibody Immunity Test
It’s NOT a Covid Diagnostic Test
Attomarker’s Covid-19 Antibody Immunity Test Appointment & test provides a comprehensive analysis of the antibodies you have developed against the Covid virus. It tells you about your immunity. It is not a ‘Covid Test’ that tells you if you have Covid or not and is not part of travel or symptomatic testing (which utilise Lateral Flow Rapid Antigen Tests or PCR to purely tell you if you have Covid or not).
Validated Measure of your Immunity
Attomarker’s test is the only available test that will tell you whether your antibody levels are high enough to be protective against symptomatic Covid-19 and provide guidance on just how long that protection will last. It is coupled with guidance on what your levels mean as you engage in health protection behaviours, vaccination and boosters.
A True Triple Test… and More
Attomarker’s test gives you a comprehensive Covid-19 immunity profile, telling you more about your personal immune response than any other test on the market. It will also tell you whether your antibodies are from just the vaccine or Covid itself, and whether or not you have had the Omicron variant.
Fast & Accurate
Test accuracy is measured by scientists in two ways. Sensitivity is how likely the test is to detect a positive result. Specificity shows how specific the antibodies are to COVID-19 and thus how trustworthy a negative result is. Attomarker’s Covid-19 Antibody Immunity Test achieves 95% sensitivity and 96% specificity.
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.
