Point-of-care testing (POCT) refers to medical diagnostic testing that is performed at or near the site of patient care, allowing for rapid and convenient testing without the need for sending samples to a centralized laboratory. This type of testing is typically performed with portable, easy-to-use devices that provide quick results, enabling healthcare providers to make immediate treatment decisions. POCT is commonly used in emergency rooms, clinics, physician offices, and other healthcare settings where quick diagnostic information is needed to guide patient care. This approach has the potential to improve patient outcomes, reduce healthcare costs, and increase overall efficiency in the healthcare system.
