Point-of-care testing

Definition

Point-of-care testing refers to medical diagnostic testing performed at or near the site of patient care, providing immediate results for clinical decision-making. This type of testing enhances patient management by allowing rapid detection and monitoring of conditions, often utilizing biosensors and chemical sensors for accuracy and reliability. It significantly improves healthcare efficiency by reducing the time between testing and treatment, which is particularly critical in emergency situations.
