I recently set out to compare the two meters since I like to have a back up meter to the Contour Next meter supplied by Medtronic. It is only until recently that AETNA started to approve the Contour Next glucose test strips through my insurance coverage.
So I have been using the ONETOUCH UltraMini for the last 5 years or so since it was the only meter that was fully covered by my insurance without a co-pay on my part.
The difference in readings was all over the place, but the only discernible pattern was that the Contour next Link 2.4 meter read consistently higher than the ONETOUCH UltraMini.
I personally think that the Contour Next is a more accurate meter (closer to the real blood glucose number) but the ONETOUCH UltraMini is more precise (multiple readings from one site are closer).
And this is important since the ONETOUCH UltraMini and ONETOUCH Verio’s superior precision is key to reducing Auto Mode and sensor errors and especially eliminating the “BG Required Loop” that occurs in Auto Mode.
