Do testing strips and glucometre have an expiry date?

Q: Do diabetic supplies like lancets, metres, test strips expire? If yes, why and what can we do with the supplies if they expire?

A: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.
