Rapid diagnostic tests (RDTs) are medical diagnostic tests that are designed for quick and easy detection of various diseases or conditions. These tests are often portable, simple to use, and provide results rapidly, enabling healthcare providers to make immediate treatment decisions. RDTs are commonly used in settings where quick diagnosis is crucial, such as in remote areas, resource-limited settings, or during outbreaks of infectious diseases. They play a vital role in early detection, monitoring, and controlling the spread of illnesses.
