The number of devices and operators complicates the oversightĪnd practical management of POCT. Monitoring is required not only of POCT quality but also of Quality and over-utilization that raise the cost of care. The convenience of POCT too often results in poor Outcomes are realized depends on the balance of quality andĬlinical need. Presents the opportunity for improved care, but whether beneficial

POCT devices are more portable thanĬentral laboratory instrumentation and have therefore foundĪpplication in medical transport vehicles like helicopters,ĭespite its portability and apparent simplicity, POCT isĬomparable to other laboratory tests and faces similar Populations, like the emergency room, operating rooms, or intensiveĬare units, as well as outpatient clinic, physician’s office, and Point-of-care testing can meet critical therapeutic needs for selective inpatient In a spare utility room on the ward or even on a mobile cart. The patient’s bedside for analysis, or specimens can be collectedĪnd carried to stationary POCT equipment in the patient’s bathroom, These terms describe the considerable variation Other names for POCT include: near-patient, decentralized,Īncillary, alternate site, patient-focused, bedside, satellite, and POCT can be defined as “diagnostic testingĬonducted close to the site where clinical care is delivered”. Point-of-care testing (POCT) is an alternative to central or core Future expansion of POCT will highlight the importance of the laboratory and develop new, evolving roles for the laboratory consultant in direct patient care. Only through participation of the laboratory on interdisciplinary management teams can the utilization of POCT be optimized for patient benefit. The potential of point-of-care testing for faster test results does not necessarily guarantee improved patient outcomes. Quality assurance of POCT requires an appreciation of the technical and operational factors that can influence the testing process. Delivery of laboratory testing outside the laboratory exposes a device to a variety of environmental, technique and patient factors that can adversely affect the analysis. Devices today are more portable, require less blood, and have computerized information management.ĭespite its popularity, point-of-care-testing does not necessarily yield laboratory-comparable results. Due to increasing healthcare pressures for faster turnaround of laboratory results and the development of a broader menu of testing devices, POCT is growing in popularity. Point-of-care testing (POCT) is a delivery option for performing laboratory testing closer to the patient.
