Product Description

 

A CE marked laboratory test for IgG antibodies to the SARS-CoV-2 virus to show whether you have been infected with coronavirus in the past. Do not take this test if you think you currently have COVID-19 or want to diagnose a current COVID-19 infection. It is not yet known whether a positive result means that you are immune to coronavirus or, if you are immune, how long that immunity will last.

Please note: This test is not for sale to, or to be used by, anyone under the age of 18.

  • Finger-prick blood sample
  • 1 biomarker tested
  • 3 working days’ turnaround

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.

TEST DESCRIPTION

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. We do not yet know 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.

TEST PERFORMANCE

This serology blood test has been developed by 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.  We advise taking the test 21 days after the onset of symptoms. This is because our laboratory has reported a slight increase in the chances of finding detectable antibodies in samples taken between 17 and 21 days after the onset of symptoms.

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 test has not yet been evaluated on people who are infected with other viruses in the coronavirus family, so it is not yet known whether these could cause a false positive result.

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.

Your anonymised data may be used to help UK agencies and other organisations understand the prevalence of coronavirus within the UK population.

The guidance for the turnaround time of results from this test is 3 working days from the time your sample is received at the laboratory. This excludes weekends and bank holidays. It is an estimate only and your results may take longer during busy periods.​

SPECIAL INSTRUCTIONS

This test must be taken at least 21 days after you first developed symptoms of COVID-19. If you have not had any symptoms then it should be taken at least 28 days after your last exposure to the virus.
