Antibody testing allows you to understand whether you have the IgG antibodies for COVID-19.
Following recent advice from the MHRA antibody testing must be undertaken by a venous blood sample.
IgG antibodies develop in most patients within 7 to 10 days after symptoms of COVID-19 begin.
IgG antibodies remain in the blood after an infection has passed.
These antibodies indicate that you may have had COVID-19 recently and have developed antibodies that may protect you from future infection. It is unknown, at this point, how much protection antibodies might provide against reinfection.
The antibody test should be undertaken ≥ 12 days after your first symptom.
A negative result means that there are no antibodies present at the time of the sample being taken.
A positive antibody test will tell you whether you’ve previously had the virus that causes COVID-19 and that your body has produced an immune response.
- Specificity – 99.24 % (the probability of the assay of scoring negative in the absence of specific IgG antibodies).
- Sensitivity – 100% (the probability of the assay of scoring positive in the presence of the specific IgG antibodies ≥12 days post symptom onset).
- CE registered.
Samples can be posted as a Category B (UN3373) with necessary packaging, if required.
