Learn more about our COVID-19 Antibody Test
Our IVD TUV certified and CE marked medical devices tests your blood for the presence of antibodies that your body has produced in response to being exposed to the virus (specifically IgG and IgM) and successfully recovered from the virus.
The Science behind our tests
- Immunoglobulins (antibodies) are produced by B-cells (a type of white blood cell) in response to the infection of the pathogen, such as SARS-CoV-2.
- Immunoglobulins bind to specific antigens on the pathogen, to ‘flag’ the pathogen as foreign.
- A secondary immune response is triggered to attack and remove the pathogen.
In the case of COVID-19, as symptoms begin to appear, immunoglobulin M (IgM) rises in the blood to detectable levels, 5 to 7 days after infection and remain detectable for some time. Immunoglobulin G (IgG) is produced to bind to specific markers on the pathogen. Its levels rise after 7 days and show exposure to SARS-CoV-2.
When to get tested for COVID-19
The COVID-19 antibody test becomes more useful over time. It takes a few days for the body to start producing antibodies. That’s why we recommend taking the antibody test 14+ days after the onset of symptoms.
By comparison, the detection rate for the PCR swab test decreases over time. This makes it a less useful tool for understanding if you have had the virus if you wait too long to get tested.
If you are worried that you might still be infectious, it is advised that you take both the PCR swab test and the antibody test to confirm your results.
Accuracy of Our COVID-19 TEST
Our gold standard IVD TUV certified and CE marked medical devices provide extremely precise results on the day of testing (same-day results).
98% overall accuracy
This level of accuracy is achieved through the use of high sensitivity Automated Immune Fluorescence Assay (AFIA) machines that are used to analyse and produce each result.
Unlike “at home” style rapid test kits, our test uses a more scientific approach. The results from our test go beyond just a simple positive (+) or negative (-) answer. Our AFIA machines will give you a Cut-Off Index (COI) value for your IgM and IgG antibodies.
