The monitor would be most beneficial for patients who cannot obtain standardized laboratory values secondary to either financial or transportation constraints.
It appears that A1c Now may provide adequate accuracy and be useful for some patients. Various conditions, including cancer, can impair normal RBC production and destruction, yielding a potentially altered HbA1c level (Wright & Hirsch, 2012). One patient's value would have resulted in a different clinical decision if the decision were based on the A1c Now value. In the past 5 years (thus for 10 surveys), the low reference A1C range has been between 5.1 and 6.6, the medium range between 5.65 and 7. We found that the most accurate A1c Now values were within a range of 6-8%.
The A1c Now monitor showed good correlation (r = 0.758) to the standardized laboratory test. An analysis evaluating both clinical and statistical significance was completed at the end of the study. Patients were required to obtain both a standardized laboratory HbA1c evaluation and a point-of-care A1c Now value within a week of each other. All patients with diabetes who attended our clinic were invited to participate in the study. Twenty-three patients who had type 1 or 2 diabetes were identified from our pharmacy-run diabetes clinic at a primary care clinic as needing HbA1c evaluation based on the American Diabetes Association guidelines. To compare a point-of-care HbA1c monitor with standardized laboratory testing. Point-of-care HbA1c monitors are relatively new, and there are few published data on their accuracy. Glycosylated hemoglobin (HbA1c) evaluation is an accepted standard of care for assessing diabetes control.
