Do testing strips and glucometre have an expiry date?

Question
Do diabetic supplies like lancets, metres, test strips expire? If yes, why and what can we do with the supplies if they expire?
Expert Answer
D
Strips have a expiry date on the bottle but once opened should be consumed in a span of three months time. Nowadays some of the bottles have a packing of 10 as well. Meters do not have expiry but from time to time these should be calibrated. Lancets also have a expiry on the packing. After expiry strips and lancets should not be used.
