We made a huge mistake after almost 5 years of diabetes testing. David had a few meter kits that he preferred that only hold small 25 strip containers. Over the past twelve months we had to change from a BD Link to a Bayer Contour Link so that his meter would continue to talk to his pump after finding that BD strips are becoming impossible to find.
On making the meter change, David was not prepared to make the kit change. The container for number of strips with Bayer is larger to accomodate 50 of 100 strips. The new meter kit is 2 x`s the size that he was comfortable with. The CONSEQUENCE - OUR ERROR - we started tranferring strips from new Contour containers to old BD containers. A few weeks ago, David started to get a lot of weird meter reading feedback. Exceptional lows that were not backed up by how he felt together with exceptional highs. We called the Bayer help line and after going through a series of telephone diagnostics were assured that the meter is responding correctly, but the strips are compromised. The old containers have expired, after months of re-use, we were basically throwing new strips on the counter and picking them up for later use by re-using the small containers. We were getting a reading, but a totally unreliable reading.
It turns out that it is not simply expiring strips, but expiring containers for strips that one needs to be concerned about. BE CAREFUL, I DO remember reading way back when not to move strips from one container to another, but without explanation in the literature, who would guess why.
