Covid-19 Abbott Antibody Test

Antibody tests are the next step in the CV-19 battle

We can now offer testing for Covid-19 antibodies, the test is carried out in a laboratory and has a 99.9% detection rate for antibodies.

Our COVID-19 Abbott Test or our IgM & IgG Antibody Home Sample Kit is available now and will be dispatched the same working day if ordered by 4pm

Test at least 14-21 days post onset of symptoms for most reliable results.

A recent study by the National COVID Scientific Advisory Panel concluded that the performance of current LFIA devices is inadequate for most individual patient applications, however ELISA and CLIA tests like the ones we are using can be calibrated to be specific for detecting and quantifying Covid-19 IgM and IgG antibodies, and are highly sensitive for IgG.

If you have had the IgM / IgG combined test and your IgG tests negative but there is a reading on your IgM this may mean that you have a current infection that has not yet developed antibodies and you will be advised to re-test in 7-14 days.

If the PCR test (have I got a current infection) is positive for Covid-19 and you recover, or if our antibody test is positive for IgG antibodies, the test results each indicate that you have been exposed to the virus and developed antibodies against it. There is still a great deal about Covid-19 immunity that we do not yet fully understand. For example, we do not yet know that just because someone has developed antibodies, that they are fully protected from reinfection, or how long any immunity lasts.

What do the results mean?

If your IgG test is positive it means you have had Covid-19 exposure sufficiently to make an antibody response to the virus. There is currently no scientific evidence confirming if the presence of antibodies correlates to immunity or how long the antibodies will last for.

It does suggest that your immune system reacted the way it was supposed to during the infection and that if you were to contract the virus again you would likely have a similar response.

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.

There is also a possibility that your body made an antibody response which has not been sustained and is therefore not detectable when it was tested for. Some patients with other underlying health conditions specifically related to their immune system may also not be able to mount a detectable or sustainable immune response and therefore may test negative. Please note that some people may not develop IgG antibodies even after proven infection with Covid-19 and will therefore test negative.

If you have had the IgM / IgG combined test and your IgG tests negative but there is a reading on your IgM this may mean that you have a current infection that has not yet developed antibodies and you will be advised to re-test in 7-14 days.
