Roche Quantitative Antibody Test

We provide the Roche quantitative antibody test, also known as the “vaccine antibody test”, which provides a positive or negative result and the number of antibodies you have. We recommend the Roche test for testing after having the vaccine, but it is also helpful after infection.

COVID antibody tests can show whether you have had a previous infection (IgG antibodies) or an immune response to vaccination. For a current infection, we continue to recommend a PCR COVID-19 swab which has close to 100% accuracy and can be taken while you are symptomatic at home.

During the test
  • During a COVID antibody test, a healthcare professional will typically collect a blood sample, often through a small needle prick.
  • The collected blood is then analysed to detect the presence of antibodies, specifically immunoglobulin G (IgG), which are proteins produced by the immune system in response to the COVID-19 virus or vaccination.

What does the blood antibody coronavirus test show?
Blood antibody testing tests for IgG antibodies for the COVID-19 virus. To test for an active infection, you will need a PCR swab.
We recommend testing 28 days after you started showing symptoms. If you are asymptomatic, you can have the test at any time. If you are currently symptomatic, we recommend having a PCR swab test which we can send to your home.
Instant coronavirus antibody tests are available now. We are currently using SureScreen COVID-19 antibody test kits for IgG and IgM antibodies and Abbott testing also.
The test for the previous infection is reliably accurate (99.6%). The test for the current COVID infection is a little less accurate (approximately 97 – 98%) which is why we recommend confirmation with a PCR swab. If you are symptomatic and currently ill, we recommend the PCR swab test which you can do at home with our kit.
