CORONAVIRUS (COVID-19) ANTIBODY TEST

ABBOTT COVID-19 IgG ANTIBODY TEST

Jenhams Clinic can now offer the new Public Health England (PHE) approved COVID-19 Abbott antibody test. Coronavirus antibody tests look for the presence of antibodies to SARS-CoV-2, the virus that causes the COVID-19 illness.

This highly-reliable test can tell if you have been previously infected with COVID-19, even in people who have not had symptoms of the virus. 

The test is accurate from 14 days or more after your COVID-19 symptoms began. The laboratory used by Jenhams Clinic advises waiting 21 days after the onset of symptoms as recently published evaluations by Public Health England saw a very small increase in detectable antibodies between 14 and 21 days.

When will I get my results?

Test results are usually returned within 3 working days.

How much does the test cost?

The Abbot Covid-19 1gG Antibody test costs £85

Does a positive antibody test mean that I now have immunity to COVID-19?

We do not yet know whether the presence of antibodies to SARS-CoV-2 in the blood provides any lasting immunity to future infection or any protection at all. We expect to learn more about the extent and duration of any potential immunity over the coming months.

If I have a positive coronavirus antibody test result, do I still need to follow the government guidelines for social distancing?

Yes, until we understand more about the virus and whether the presence of antibodies means that you can’t catch it again, it is important that you follow all the recommended guidelines.

How is the coronavirus antibody tests carried out?

A venous blood sample is taken by a Registered Nurse at Jenhams Clinic and sent to the laboratory for analysis

How accurate is the coronavirus antibody tests?

The test 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 SARS-CoV-2 infection in the same study.

What does a positive result mean?

A positive result means that the laboratory found IgG antibodies to coronavirus (SARS-CoV-2) in your blood. This means that it is highly likely that you have been infected with coronavirus in the past.

Who should use a coronavirus antibody test?

Coronavirus antibody test is appropriate for anyone who wants to know whether they have had COVID-19. People who have had a mild or moderate form of the disease, or who have been exposed to COVID-19 but didn’t experience symptoms at all, may want to know whether they previously had the virus. It is important to wait 14-21 days from the onset of symptoms before taking an antibody test; this allows sufficient time for antibodies to reach detectable levels. If you have had no symptoms, then this test should be taken 21-28 days after the last exposure to the virus.

I am experiencing symptoms which I think may be caused by COVID-19. Should I take a coronavirus antibody test?

No. This test is only for people who want to know if they were infected with coronavirus in the past. If you are experiencing symptoms such as a cough, shortness of breath or high temperature you should isolate yourself at home and seek guidance from NHS 111.

Will a coronavirus antibody test tell me if I have a current infection?

No. This test detects antibodies which are produced some time after an individual becomes infected.
