Test Strip Stability
"Stability testing protocols and acceptance criteria for the Contour NEXT EZ test strips were reviewed and found to be acceptable. The manufacturer claims shelf life stability and open-vial stability of 18 months at the recommended storage temperatures of 5-30°C."
I was happy to see the part about open-vial stability. That’s a fairly important thing. Some strips are much more fragile when they are outside.
