Point-of-care testing

Definition

Point-of-care testing (POCT) refers to medical diagnostic testing performed at or near the site of patient care, allowing for immediate results that can facilitate prompt clinical decisions. This approach enhances the efficiency of healthcare delivery by reducing the time between sample collection and result reporting, thus improving patient outcomes and accessibility to testing.

5 Must Know Facts For Your Next Test

1. Point-of-care testing includes a variety of tests such as glucose monitoring, pregnancy tests, and infectious disease screening.
2. POCT devices are often portable, allowing for testing in various settings such as homes, clinics, and emergency rooms.
3. The main advantage of point-of-care testing is the ability to deliver immediate results, which can significantly speed up treatment initiation.
4. Point-of-care testing can improve patient engagement by allowing individuals to participate actively in their own health monitoring.
5. Regulatory standards for point-of-care testing are crucial to ensure accuracy and reliability of test results, impacting clinical decisions.
