Acceptability of capillary blood glucose testing with Companion 2 after intensive individual patient training.

This study determined the accuracy and precision of the MediSense Companion 2 Blood Glucose Monitoring System in the hands of newly trained patients, after individual training. 101 subjects attending a diabetes clinic at a Veterans Affairs Medical Center participated in the study. Subjects were individually trained in the use of the Companion 2 system. They performed 10 practice control solution tests prior to two capillary blood glucose tests. Venous blood was collected within 15 minutes for comparative laboratory analysis. The comparisons were performed by both the linear regression and the total Grid analysis. The correlation between the first capillary blood glucose test results and the laboratory values was highly significant (r = 0.94, p = 0.0001). Total Error Analysis also revealed that the Systematic Error (SE), Random Error (RE) and Total Error (TE) were all well within the acceptable norms at two glucose levels of 5.5 mmol/(100 mg/dL) and 11.1 mmol/L (200 mg/dL); (SE < 15%, RE < 10% and TE < 15%). Therefore, this study demonstrates that Companion 2 provides precise and accurate values during capillary blood glucose testing by newly trained subjects following intensive individual training.
