One common COVID-19 test is the test for one or more of the antibodies the body creates when it encounters the COVID-19 virus. Because these tests are often Point-of-Care, rapid tests that require only a blood sample they may appear to patients as an easily accessible and useful tool for guiding their actions in the pandemic. However, serologic antibody tests should not be offered to patients in normal practice under nearly all circumstances. They are useful in narrow diagnostic settings in later stage infections and they serve an important public health function, but they are not of benefit to patients and may in fact give false and potentially harmful information to patients of moderate health literacy.
