Point of care testing: testing the system?

Point of care testing is changing for the better the way we practice medicine. Whether it is an anesthesiologist doing a blood gas in the operating room, a nurse measuring serum glucose in the home or on the unit, or an intensive care nurse testing by the bedside before calling an intensivist, newer instrumentation provides for a limited number of quality tests to instantly add value to the critical decision-making process of modern staff. This movement is a true paradigm shift that will reduce unnecessary testing, provide timely measurement of critical values and avoid unnecessary and catastrophic mistakes.
