Point-of-care testing

Definition

Point-of-care testing refers to medical diagnostic tests that are performed at or near the site of patient care, allowing for rapid results and immediate clinical decisions. This approach reduces the time between testing and treatment, improving patient outcomes and enhancing healthcare efficiency. The integration of biosensors into these devices has led to significant advancements in their accuracy and ease of use.
