Rapid diagnostic tests (RDTs) are a type of point-of-care diagnostic, meaning that these assays are intended to provide diagnostic results conveniently and immediately to the patient while still at the health facility, screening site, or other health care provider. Receiving diagnosis at the point of care reduces the need for multiple visits to receive diagnostic results, thus improving specificity of diagnosis and the the chances the patient will receive treatment, reducing dependence on presumptive treatment, and reducing the risk that the patient will get sicker before a correct diagnosis is made. Rapid tests are used in a variety of point-of care-settings—from homes to primary care clinics or emergency rooms -- and many require little to no laboratory equipment or medical training.
