Blood-Glucose Meters
by Editors of
Our AssessmentA series of volunteers, some of whom have diabetes, help lab technicians test 25 blood glucose meters for Consumers' Union. Previous editions of this report did not include accuracy ratings, but the newest edition does. Testers also evaluate the blood glucose meters on their convenience and consistency; full details are available to subscribers.
The Accuracy of Home Glucose Meters in Hypoglycemia
by A. Sonmez, M.D., et al.
Our AssessmentA large team of researchers tested five different blood glucose meters designed for in-home use to find out how well they detected hypoglycemia. The researchers tested finger capillary and forearm venous blood samples with the Optium Xceed, Contour TS, Accu-Chek Go, OneTouch Select and EZ Smart. The results were compared to laboratory analysis of venous samples using the hexokinase method. The researchers note that although all five meters failed the test to some extent, the Accu-Chek Go, Optium Xceed, and Contour TS were significantly better than the other two meters tested, and the Accu-Chek Go and OneTouch Select offered better capillary and venous consistencies than the other models.
Accuracy and Prevision Evaluation of Seven Self-Monitoring Blood Glucose Systems
by Dr. CY Kuo, et al.
Our AssessmentResearchers evaluate seven blood glucose monitoring systems for accuracy and precision, including the OneTouch Ultra2, Ascensia/Bayer Contour and Accu-Chek Performa. Of the monitors tested, only three fulfilled the minimum ISO criteria for accuracy. Just one, the Bionime Rightest GM550, meets the tight criteria of being within 15 percent in either direction of the actual results. The researchers conclude that "manufacturers have to strive to improve accuracy and precision."
Accuracy Evaluation of Five Blood Glucose Monitoring Systems Obtained from the Pharmacy: A European Multicenter Study with 453 Subjects
by Cornelius Tack, M.D., et al
Our AssessmentResearchers test five recently introduced blood glucose meters under everyday conditions, comparing the results against a clinically administered test. Three meters performed well, with the FreeStyle Lite showing the lowest mean absolute relative differences. The other models tested were the OneTouch UltraEasy and the Contour. Abbott Diabetes Care, which manufactures the FreeStyle models, was involved in the design and analysis of the tests.

Blood Glucose Meters 2013
by Editors of Diabetes Forecast
Our AssessmentAlthough the editors do not assign comparative ratings to individual blood glucose meters, they provide a number of helpful charts, including one showing which meters work best at low or high temperatures, plus charts comparing memory capacity and the cost of test strips (based on MSRP).

Blood Glucose Meters 2014
by Lindsey Wahowiak
Our AssessmentThe author discusses the importance of blood glucometer accuracy for consumer safety and notes that the FDA has not yet adopted the updated ISO standards (released in 2013).
System Accuracy Evaluation of 43 Blood Glucose Monitoring Systems for Self-Monitoring of Blood Glucose According to DIN EN ISO 15197
by Guido Freckmann, M.D., et al
Our AssessmentThe researchers evaluated 43 blood glucose monitoring systems for their conformity to ISO standards for CE-labeled glucometers. Of these, 27 passed; we've listed those that were accurate at least 99 percent of the time. Several notably poor performers were the SeniorLine GM210, the GluxoRX TD-4230 and the Glucohexal II.
Performance Variability of Seven Commonly Used Self-Monitoring of Blood Glucose Systems: Clinical Considerations for Patients and Providers
by Ronald L. Brazg, M.D., et al
Our AssessmentResearchers evaluate seven blood glucose monitors for their compliance with the current and proposed ISO criteria for blood glucose monitors. Just one, the Accu-Chek Aviva Plus, meets the proposed criteria with all three lots of test strips tested. The others, which show greater variations, are the Advocate Redi-Code, Element, Embrace, Prodigy Voice, TRUEbalance and WaveSense Presto.
Lot-to-Lot Variability of Test Strips and Accuracy Assessment of Systems for Self-Monitoring of Blood Glucose According to ISO 15197
by Annette Baumstark, Ph.D., et al
Our AssessmentResearchers tested four lots of test strips for each of five blood glucometers with the goal of finding out how consistent results were between lots. Only two of the five meters tested met the criteria in DIN EN ISO 15197:2003 with each lot of test strips tested: The Accu-Chek Aviva and FreeStyle Lite. The monitors whose test strips did not pass were the GlucoCheck XL, Pura/mylife Pura and OneTouch Verio Pro.
Clinical Assessment of the Accuracy of Blood Glucose Measurement Devices
by A. Pfützner, et al.
Our AssessmentResearchers compared the BGStar and iBGStar against four other blood glucose meters -- the Accu-Chek Aviva, FreeStyle Freedom Lite, Bayer Contour and OneTouch Ultra 2 -- using the glucose oxidase method. They note that using the glucose oxidase method "may be considered to be a limitation in light of glucose hexokinase-based meters." A total of 106 people participated in this study. Half were men, half were women; 32 of the participants had type 1 diabetes, 34 had type 2, and 40 were completely healthy. All of the meters tested, including the iBGStar, were described as very highly accurate; 99.5 percent of the iBGStar's readings were within the clinically acceptable areas.
Glucose Meters: A Review of Technical Challenges to Obtaining Accurate Results
by K. Tonyushkina, M.D., et al.
Our AssessmentThe authors examine how blood glucose meters work. They also examine the inherent difficulties this method presents toward establishing accurate measurements in inpatient and outpatient settings and identify the most likely causes of inaccurate readings. The researchers conclude that "Skill of the user, not the technical specifications of the instruments, is the most significant source of blood glucose errors, especially in outpatient settings."
Evaluating Glucose Meters: Talk is Cheap, But Access is Golden
by Connie Kleinbeck, RN
Our AssessmentDiabetes is a leading cause of blindness, but most blood glucose meters require sight to operate. The National Federation of the Blind lists and explains several talking blood glucose monitors that can help blind people test their blood glucose independently. The Prodigy Voice offers the widest array of audible instructions and feedback, and it earns the highest praise from diabetes educator Connie Kleinbeck.
Diabetes and Visual Impairment: An Update on the Blood Glucose Monitor Market
by Darren Burton
Our AssessmentThe American Foundation for the Blind thoroughly tests two talking blood glucose meters -- the Prodigy Voice and the SensoCard Plus -- for ease of use by blind or low-vision people. Testers like both blood glucose monitors, but they find the Prodigy Voice "slightly more accessible and usable" for people with impaired sight.
Blood Glucose Meters That Are Accessible to Blind and Visually Impaired Persons
by Mark M. Uslan, et al
Our AssessmentThis study looks at five blood glucose meters designed for use by visually impaired people, including several models from Prodigy and Advocate. The Prodigy Voice is the only one "fully usable by blind and visually impaired persons." The study is excellent, but it's three years old, and it doesn't include some of the newest models on the market.

A New Talking Meter
by David Mendosa
Our AssessmentDavid Mendosa, a journalist with type 2 diabetes, writes extensively about the disease on his own website and in other publications. Here he reviews the Solo V2 talking blood glucose meter. Unlike other talking meters, the Solo V2 audibly warns the user if there's not enough blood on the test strip, preventing false results.

Our AssessmentA. Paul Chous is an optometrist who has type 1 diabetes and who specializes in diabetes eye care. He tests Prodigy blood glucose meters for several weeks and especially likes the Prodigy Voice, which was designed with the help of visually impaired and blind patients. He says its tactile buttons "allow easy operation by even totally blind people with just a little practice."

Our sells fewer brands of blood glucose meters than, and it collects fewer user reviews of diabetes testing equipment. Just two models receive a 4.5-star or better rating after at least 10 user reviews. (Two Accu-Chek models appear to have similar ratings after hundreds of reviews, but the vast bulk of those reviews are actually imported from the Accu-Chek website.)
