With results in only 10 minutes, the COVID-19 antibody test is a finger prick test which identifies if the body has developed an antibody response to a COVID-19 infection. It is NOT a viral test to identify if you currently have COVID-19. The test is highly sensitive and specific detecting IgG antibodies, however no test can be 100% accurate.
It has a sensitivity greater than 99.9% - this means that among 1,000 people who have had coronavirus, almost 100% of them will correctly test positive.
It has a specificity of 98% - this means that among 1,000 people who have not had coronavirus, 980 of them will correctly test negative.
Please note that until proven, the presence of COVID-19 antibodies does not mean that you have immunity against further infection of the virus.
The antibody test should only be performed 21 days after recovery from COVID-19 symptoms or 28 days after contact with someone with COVID-19 symptoms. This is to ensure that there has been enough time for detectable antibodies to have built up in the blood.
