CONCLUSION
Multiple factors affect the accuracy of currently available glucometers. Consideration of patient comorbidities, medication use, operational technique, and the conditions under which test strips are stored is important when utilizing glucometer data to make medication adjustments in diabetes management. It is important to refer to specific glucometer and test strip manufacturer device labeling to help select the appropriate glucometer for a particular patient.
The case presentation from 2009, involving falsely elevated blood glucose readings in a patient using a GDH-PQQ meter while receiving icodextrin peritoneal dialysis solution, highlights the importance of background knowledge of glucometer operational mechanisms. For a full list of test strips that are compatible with icodextrin peritoneal dialysis solution, please see the Country-Specific Glucose Monitor List at www.glucosesafety.com.5
Examples of specific GO meters include the OneTouch Ultra, iBGStar, and ReliOn meters. Although the GO meters do not cross-react with icodextrin, these meters should be avoided in patients receiving supplemental oxygen, due to the potential for falsely lowered readings.
The GDH-FAD, GDH-NAD, and Mut Q-GDH test strips may be used in patients receiving icodextrin peritoneal dialysis solution and those receiving supplemental oxygen.3,5 Examples of GDH-FAD meters include most currently available FreeStyle meters, Bayer Contour meters, and One Touch Verio meters. The Precision Xtra meter uses GDH-NAD test strips. Most Accu-Chek meters currently use Mut Q-GDH test strips.
