Point-of-Care Diagnostics

Definition

Point-of-care diagnostics refers to medical testing conducted at or near the site of patient care, allowing for immediate results that facilitate rapid clinical decision-making. This approach to diagnostics enhances patient management by providing timely information that can influence treatment decisions, often in settings such as hospitals, clinics, and even patients' homes. The historical development of medical technology has greatly impacted the evolution of point-of-care diagnostics, leading to advancements in devices and methods that improve access to healthcare.
