  • Test at least 21 days post exposure to COVID-19/onset of symptoms.
  • This is an easy at home blood test that is sent to our laboratory for analysis.
  • It tests for IgG antibodies to COVID-19, not the virus itself.
  • IgM or IgA antibodies are not tested.
  • A positive IgG result will confirm antibodies of the IgG class against Coronavirus (Covid-19). This informs us, with a high degree of confidence, that the patient has been infected by this virus at least a week before the sample was taken. The presence of IgG antibodies to a particular pathogen (infectious agent such as a virus or bacteria) usually implies a degree of immunity to further infection from the same agent. In the case of Covid-19 however, it is not known yet to what extent immunity is conferred, and if so for how long. What we can say is that having IgG antibodies to other viruses within the Coronavirus group is associated with at least short term immunity to re-infection.
  • A Negative IgG result informs us, with a degree of confidence, that it is highly unlikely that the patient has been infected by this virus up until at least a week before the sample was taken. It is possible however that the patient could have been infected and not mounted a significant immune response - either because the infection was mild and did not lead to the production of a detectable amount of antibody or because the levels have not yet risen to a detectable level. This latter explanation is more likely if the time from onset of the illness to the time of taking the sample was less than 21 days. Repeat testing in 2 week’s time or longer following a negative result may lead to a positive result if this scenario is a possibility.
  • The laboratory kit is CE marked. The laboratory is accredited through the CQC.
  • The laboratory ELISA kit was subjected to clinical testing against 2 cohorts of patients that were either healthy or had a previous RT-PCR swab positive result for COVID-19. It was found that the diagnostic sensitivity was 95% and the diagnostic specificity was 98.3%. This is an emerging illness, and more validating tests will be undertaken in time.
  • Our Expedited service consists of a Royal Mail 24 service outbound, and a tracked service return to laboratory envelope. In normal circumstances this would mean a 1 working day journey both ways, however during the pandemic this may mean delays, but it remains the best service available. Making use of a regular first class postal service would mean delays of weeks so this is the best option.
