![]() It is unknown whether COVID-19 antibodies indicate protective immunity and for how long.Ī negative test result does not rule out the possibility of an infection with SARS-CoV-2. This is how immunity happens, although it doesn’t occur with all diseases.Ī positive antibody test result may indicate previous or current exposure to an illness but should NOT be used to infer immunity status or infectivity. For example, when you get sick with chickenpox or receive the chickenpox vaccine, your blood cells respond by making antibodies that protect you from getting it in the future. Antibodies may protect you from getting the same disease again.

Currently, Dynacare offers this test in Ontario, Manitoba and Quebec only. In Ontario and Manitoba, the COVID-19 (SARS-CoV-2) Antibody Test is $80. The Spike Antibody test detects antibodies generated through natural exposure and/or post-vaccination, but cannot differentiate between the two. The Nucleocapsid Antibody test detects antibodies generated from natural exposure only. It is yet undetermined what level of antibody to SARS-CoV-2 spike protein correlates to immunity against developing symptomatic SARS-CoV-2 disease. Generally, a minimum of 28 days after the first vaccine dose is recommended before having an antibody test performed. It will not tell you if you have COVID-19 right now, and a negative result does not entirely rule out previous exposure. The test should be done 14 days or more after onset of natural infection. This test is helpful to identify patients previously infected by COVID-19 and to determine the presence of antibodies in individuals who have been vaccinated.Ĭan be used for natural exposure and/or post-vaccine. ![]() The SARS-CoV-2 Antibody Test Panel determines both presence and levels of antibodies to the SARS-CoV-2 spike protein. (OMNI Order Code: COV2AB Ontario Panel Test Code CVAB Manitoba Panel Test Code 0649) Includes Total Nucleocapsid Qualitative and Total Spike Quantitative Antibody tests. Check for the presence of COVID-19 (SARS-CoV-2) antibodies in your blood indicating a past COVID-19 natural infection, or the presence of spike total antibodies following vaccination.
