1. Study Purpose

   The purpose of this study was to determine the effects of using venous versus capillary blood and using a bedside blood glucometer versus a laboratory multichannel analyzer for the measurement of blood glucose levels. Capillary and venous blood specimens were collected simultaneously and glucose was measured at bedside using each. Half of the venous specimen was sent to the laboratory in a lithium heparin tube for further whole blood glucose estimation.

   Summary of Findings:

   Despite very strong correlations between all three glucose measurements, the average blood glucose measured in the laboratory on a venous specimen by the Dade-Behring Multichannel Analyzer (7.075 mmol/L) was significantly lower than the average capillary (7.66 mmol/L) or venous blood glucose (7.99 mmol/L) measured using a bedside Medisense Precision Plus Glucometer (both p<0.001). In addition, the average bedside venous blood glucose measurement was significantly higher than the average bedside capillary blood glucose measurement (p<0.05).
