Rapid diagnostic testing (also called rapid diagnostic tests, or RDTs) can quickly inform medical staff of results related to certain types of infectious diseases (such as influenza, Covid, STIs, gastrointestinal, or respiratory infections), at or near the point of care. RDTs are also used for travellers returning home. While they represent certain advantages (rapid, inexpensive, and easy to use), these tests are less sensitive than conventional tests, and are not always meant to replace them.
