This information is intended for use by healthcare providers, public health professionals, and those organizing and implementing testing in non-healthcare settings, such as schools, workplaces, and congregate housing. We found that this pool of antibodies could also neutralize other variants, such as Delta and Omicron, says Hastie.

Antibody trajectories following SARS-CoV-2 infection. A negative test result does not rule out the possibility of an infection with SARS-CoV-2. A: Sensitivity is the ability of the test to identify people with antibodies to SARS-CoV-2. A highly specific test will identify most people who truly do not have antibodies, and a small number of people without antibodies may be identified as having antibodies by the test (false positives).
