Abstract:
To assess the accuracy of venous blood sampling obtained from peripheral intravenous infusion lines, peripheral saline locks, and by peripheral venipuncture, dual blood samples from 55 hospitalized patients were compared for test reliability. Tests included complete blood cell counts, electrolyte studies, and general survey panels. Results showed that within certain limitations, blood sampling from a wide range of peripheral indwelling devices is reliable for many routine blood tests.
