Although central laboratory testing has been the norm for the last few decades and point-of-care testing (POCT) is considered an emerging area, physicians were performing POCT long before the existence of central laboratory testing. As medical directors of POCT programs, pathologists need the basic knowledge and skills associated with directing laboratory-based testing programs as well as additional knowledge and skills about testing at the point of care. Although the essential elements of quality testing are the same for laboratory-based and POCT, the enormous variety of settings, technologies, and workers involved present unique challenges.
