Evaluation of One Touch HORIZON--a highly affordable glucose monitor

Despite the growing evidence on the benefits of self-monitoring in diabetes, the use of these meters has been low in developing countries, particularly India. Cost seems to be the major constraint. The aim of the present study is to evaluate the accuracy of One Touch HORIZON an affordable glucose meter with laboratory assessment of blood glucose.

100 subjects with diabetes over the age of 18 years were recruited from the MV Diabetes Specialities Centre, Chennai. All the study subjects had their fasting blood tested for glucose in One Touch HORIZON by finger prick. Fasting blood glucose was also assessed in YSI 2300 STATPLUS (Yellow Springs Instruments, Ohio, USA) glucose analyzer. The Parke's Error Grid model was used to assess the accuracy of the meter against YSI plasma glucose values.

Of the total 100 study subjects, 97 were Type 2 diabetic subjects and three were Type 1 diabetic subjects. 62% of the study subjects were males. 89% did not perform SMBG and only 2% of the diabetic subjects performed SMBG daily. The Parke's Error Grid analysis revealed 97% of results to be in Zone A when patient performed the test, 99 - 100% in Zone A when clinical staff performed the test indicating excellent accuracy and precision.

One Touch HORIZON meter is an affordable meter with good accuracy and precision, specifically designed to cater to the needs of diabetic patients in developing countries.
