Antigens are molecules that trigger the production of antibodies by inducing an immune response.
If you are displaying COVID-19 related symptoms, the antigens in your body will be detectible for these types of tests.
If you are not displaying symptoms but feel as though you've been exposed, we suggest waiting at least 72 hours after exposure before coming in for a Rapid Antigen Test.
If exposure leads to an infection, 98% of people will show symptoms in under 11.5 days, with the over/under for immune response being 5.1 days.
Antigen levels before symptom onset, or late in the course of infection, may be below the limit of detection of virus of the test.
However, false negative test results are unlikely when an antigen test is used according to the manufacturer’s instructions.
