The study used approximately 21,000 data points from more than 200 different OneTouch Select Plus test strip batches, routinely and regularly sampling across 3 years of production to assess product accuracy, according to the manufacturer's press release.

Investigators evaluated the test strips with a minimum of 100 subjects with diabetes, and then compared the readings with capillary blood samples collected at the same time.


The study found that 97.6% of the batches met the accuracy criterion of 97.1-98.1% by year. The product also demonstrated clinical accuracy across all 7 glucose ranges. Under combined conditions of hematocrit and glucose extremes, 97.7% of values were clinically accurate.


"In this study, results are based on more than 21,000 blood glucose meter readings gathered in a clinical setting and paired against corresponding reference instrument readings — all using OneTouch Select Plus test strips – over a period of years,” said Guido Freckman, MD, medical director of the Insitut für Diabetes-Technologie Forschungs- und Entwicklungsgesellschaft mbH an der Universität Ulm, in a prepared statement.

“This sort of continuous, systematic testing methodology enhances the picture of performance given by other accuracy studies, including those I have authored."


This is not the first time that researchers have tested OneTouch products. In both an April 2017 study and a March 2018

study, experts tested the OneTouch Verio Flex platforms and found consistent high accuracy.


According to the authors of the most recent study, due to publication of sometimes-conflicting data presented within ad hoc blood glucose monitoring clinical accuracy evaluations, they recommend that manufacturers adopt similarly robust and systematic surveillance programs to better safeguard patients.
