Current Status of Clinical Application of Point-of-Care Testing.

CONTEXT.—: The clinical applications of point-of-care testing (POCT) are gradually increasing in many health care systems. Recently, POCT devices using molecular genetic method techniques have been developed. We need to examine clinical pathways to see where POCT can be applied to improve them. OBJECTIVE.—: To introduce up-to-date POCT items and equipment and to provide the content that should be prepared for clinical application of POCT. DATA SOURCES.—: Literature review based on PubMed searches containing the terms point-of-care testing, clinical chemistry, diagnostic hematology, and clinical microbiology. CONCLUSIONS.—: If medical resources are limited, POCT can help clinicians make quick medical decisions. As POCT technology improves and menus expand, areas where POCT can be applied will also increase. We need to understand the limitations of POCT so that it can be optimally used to improve patient management.
