Some meter strip systems have filters built in to block interferors as well as cope better with water and oxygen. The accucheck meter got me into serious trouble because of its inaccuracy at hypoglycemic ranges which sent my blood glucose bouncing like crazy. I too had difficulty in finding a test strip supplier. All seem to work well. Thank you for a very informative discussion. Meters are pretty much at the limits of their technology.
Also, how many do we need?
Effect of adverse storage conditions on performance of glucometer test strips.
The glucose test strips are incorporated into a drum that is stored in the Accu-Chek meter itself. The ways we use them also affect accuracy. Then we need to ask did we do something different today? Just my two cents worth. If you were to divide these costs between all the users it would be way less than what they charge! Some meter strip systems have filters built in to block interferors as well as cope better with water and oxygen. Even the same brand of strip will vary from batch to batch and even within the same container.
