Point-of-care testing refers to medical diagnostic tests that are performed at or near the site of patient care, rather than in a centralized laboratory. This approach allows for immediate results, enabling quicker decision-making and treatment. Common examples include blood glucose monitoring and rapid tests for infections. These tests are designed to be simple and efficient, often using portable devices that can be operated by healthcare professionals or even patients. By providing timely information, point-of-care testing can improve patient outcomes and streamline healthcare processes, making it an essential tool in modern medicine.
