Hello, We are very new to diabetes - our son was just diagnosed 2 months ago. We are running through test strips like water and am beginning to have a problem getting more through insurance. We use the One Touch meters and they package their test strips in vials of 25. We were told that everytime we open a new vial, we should use the control solution to check to make sure they are working. How necessary is this? I am asking because I am looking to conserve test strips anyway we can - we sometimes go through 12+ a day. Between checking a lot, and inevitably once (or more than once) per day we don't get enough blood in, get an error, and have to throw it away. We ran through a 90 day supply in less than 50 days. We do not have this problem with lancets - I admit we often don't change the lancet everytime out of sheer laziness - particularly in the middle of the night. Thanks in advance for your help.
