Find out about previous exposure to COVID-19 with this lateral flow antibody test
This test, manufactured by Surescreen, allows for the rapid detection of IgM and IgG antibodies at point of care. IgM antibodies appear in the blood as early as 7 days from onset of symptoms, whilst IgG become detectable later, usually at 21 days. This lateral flow will confirm a potential past exposure to SARS-CoV-2, the virus that causes COVID-19, in under 10 minutes.
Note: this test is only available for purchase to companies and organisations that have a resident healthcare professional. When registering with us, we will verify your status and subsequently enable the purchase of this test if your status is approved.

"Easy to collect the sample, easy to post it, results two days later. And excellent customer service!! Thank you, you're doing an amazing job!"
“I could not have had a smoother experience. Ordered a test on a Friday morning. It was dispatched an hour later and arrived on Saturday morning. Took the test on Wed and got my results 48 hours later."
This test requires only a few drops of blood which can be obtained by a healthcare professional using finger prick lancets. It is easy to use if you have good blood flow at your finger tips.
If you have low blood pressure or low circulation in your hands, which may present as your fingers going unusually white in cold winter weather, this test may not work for you.
Our immune response to COVID-19 infection leads to the production of immunoglobulins, which attach to the virus and activate the rest of the immune system to attack and clear the virus. Immunoglobulin M (IgM) antibodies have been detected as early as day 5 after symptom onset, while the median time for them to appear is day 10‐13. Immunoglobulin G (IgG) antibodies are usually produced at a later stage in the infection at around day 12‐14 days after symptoms, and subsequently remain for a period of time.
The general understanding of how antibody levels ramp up following infection as described above is clear, however research continues as to how long antibodies remain detectable following infection. The general consensus is that antibody levels and their longevity are linked to the severity of infection, and that the level will diminish over time.
It is not certain that every individual who was infected with SARS-C0V-2 will create an antibody immune response, and that it is still detectable at a specific number of months post infection.
This test shows you whether or not you’ve had COVID-19 in the past, by detecting antibodies in your blood. The test will however not tell you whether or not you are immune to the virus, and whether or not you currently have COVID-19. To test for current infections, you need to use a PCR Viral RNA, or Antigen test.
This means that the test has been validated by the manufacturer and is in line with the health and safety standards of the European Economic Area.
Yes, you can still do this test. Research shows that up to 30% of people who have had COVID-19 have not experienced symptoms
This test uses the Surescreen COVID-19 Lateral Flow which has been extensively validated by independent organisations that complement the manufacturers validation work as part of CE marking the lateral flow device. Organisations that have assessed the product include:
For reference, a key report is from Guy’s and St. Thomas’s hospital that compared multiple serological (antibody) tests in a comparative study of 503 clinical patients with varying degrees of COVID-19 illness severity. The report is available as a pre-print paper here.
