Measuring COVID-19 IgG Antibodies


COVID-19 IgG antibodies increase after exposure to the COVID-19 virus and reach a peak of 100% detectability 20 days after the onset of symptoms. If you have had symptoms of coronavirus, then it is best to collect your blood sample more than 20 days after your symptoms started.

  • The test will not be offered to those who are pregnant or breastfeeding.

  • Suitable for people over the age of 18.


Please note: test results will be described as either negative, borderline or positive.

A positive or borderline result does not mean that you won’t catch the virus again or carry and transmit the virus onto someone else, nor does it mean that you are immune to having another COVID-19 infection in the future.
