Selecting an accurate point-of-care testing system: clinical and technical issues and implications in neonatal blood glucose monitoring.

ISSUES AND PURPOSE: Rapid identification and treatment of glucose abnormalities is crucial in the prevention of potentially devastating neurological injury in neonates. Choice of a point-of-care glucose testing system must consider accuracy, clinical advantages, and data management capabilities. CONCLUSIONS: The benefits and limitations of point-of-care testing must be weighed against the time delay of central laboratory testing. PRACTICE IMPLICATIONS: Considerations in selecting a point-of-care blood glucose monitoring system include accuracy, precision, versatility, and the potential for cross infection and blood loss. When a system is selected, studies must be done to identify potential sources of error and confirm the utility and accuracy of the system in the identified population.
