Have you experienced symptoms which you think were caused by COVID-19 but would like to make sure?

Have you had a positive PCR test for COVID-19 and would like to know whether you have developed antibodies?

Or do you wonder whether you have been exposed to the virus even though you haven’t had symptoms?

Special instructions

This test must be taken at least 21 days after the onset of symptoms or 28 days after contact with an infected person. It can help you understand whether you have developed antibodies to the SARS-CoV-2 virus, which causes COVID-19.


This test looks for immunoglobulin G (IgG) antibodies to SARS-CoV-2, the virus that causes COVID-19. Your body produces antibodies as part of its immune response to an infection. These antibodies normally become measurable from 7 – 14 days post-infection and can indicate whether you were previously infected with the virus.

A positive result means that you have detectable levels of IgG antibodies in your blood. It is not yet known whether this means that you are immune to coronavirus or, if you are immune, how long that immunity will last.​

Do not take this test if you are currently experiencing symptoms of COVID-19. Please contact 111 for guidance on what to do and to discuss testing options for a current infection.​

NHS staff who are eligible can obtain a discount on this test through Blue Light Card. No other discount codes or offers can be used on this test.

The Chief Medical Officer in Scotland has advised against on-demand antibody testing. For the time being, this test is not available in Scotland.

Test performance

This serology blood test has been developed by Abbott Laboratories, a global medical devices and healthcare company. It is a laboratory test using chemiluminescent microparticle immunoassay (CMIA) technology. It is CE-marked which means that it conforms with European standards for the design and manufacture of such tests. The manufacturer states that in its validation study the test detected antibodies in 100% of confirmed coronavirus cases when the sample was taken at least 14 days after symptoms first developed. The test produced a negative result in 99.6% of samples from people who did not have the infection in the same study.

The laboratory processing this test conducted its own evaluation of the assay. The test produced a positive result in 98.5% of samples from people known to have been infected with coronavirus (132 samples tested) and produced a negative result in 99.5% of samples with no infection (186 samples).

Public Health England (PHE) has approved the use of this test by the NHS using samples taken from a vein in the arm. PHE has conducted its own evaluation of the test using 82 positive samples (from people who tested positive to coronavirus on a PCR swab) taken at least 14 days after the onset of symptoms and 395 negative samples (taken before mid-2019). PHE’s study showed the test correctly identified people who had been infected in 93.9% of cases where 14 or more days had elapsed since the onset of symptoms and correctly produced a negative result in people with no infection in 100% of cases.

This test may not accurately detect antibodies in people who have compromised immune systems because their antibody response may be slower or weakened. This may affect the reported results above. These people may have immunodeficiency diseases, infections such as HIV, or be taking medications that suppress the immune system.

The manufacturer did not evaluate the test on people who had been infected with other viruses in the coronavirus family. The PHE evaluation contained a number of samples with positive seasonal coronavirus results in its negative sample population. None of these samples produced a positive result when tested by PHE.

A negative result does not exclude a current infection particularly in those who have recently been exposed to SARS-CoV-2, or in those who currently have symptoms of COVID-19, because antibodies to the virus may not have reached detectable levels at this point.

Can I get a negative antibody result even if I have had covid-19 infection?

There is a small possibility that you have had coronavirus yet have not developed antibodies. This can happen if you had a very mild case of COVID-19 or did not develop any symptoms. There is also some emerging evidence that a minority of people who had a negative antibody result may have had a different type of immune response controlled by T cells, a type of white blood cell that recognises infected cells. Our test measures IgG (immunoglobulin G antibodies) which is the most common type of antibody found in the blood after an infection. As our immune systems are highly complex and this virus is novel, it takes time for the global medical science community to develop the best understanding of COVID-19 immunity. More recently research from the Karolinska Institutet in Sweden found that people with mild or no symptoms had developed “T-cell” immunity despite testing negative for antibodies. This study is yet to be published and peer reviewed by the science community, but it has no doubt provoked further debate about how our immune systems respond to the virus. Before we can jump to any solid conclusions, further evaluation of this is needed with more research. Until we know more about whether antibodies or T-cells confer any protection against coronavirus, it is not safe to assume that you have acquired immunity to COVID-19.

Is my negative test result reliable if my suspected infection was over 2 months ago?

If you develop an antibody response to the virus, it is most likely to show up as a positive result 2-3 weeks after the onset of symptoms. Further research is currently being conducted to confirm what happens to these antibody levels beyond 5 weeks. At present we are not in a position to reach any clear conclusions as whilst some studies have shown the antibody response can disappear after 2-3 months, others have concluded this can last for longer than 2 months. In short, a negative antibody result cannot completely rule out a previous infection.

Since the first case of COVID-19 was first reported to the World Health Organisation in December 2019 knowledge about this virus has been ever evolving. Research is ongoing and there is still much more to learn about the long-term effects of this virus on our health and immunity. It is also important to note that amidst our focus on this pandemic we must not forget that the symptoms of coronavirus can be caused by other viruses, allergies and medical conditions. If you are still experiencing symptoms which cause you concern, we recommend you discuss them with your GP.
