Hello- I am new to this as my cat was just diagnosed last week with Diabetes. It has been a whilwin of vet visits etc. So today we went to learn how to do home testing and give the injections. Mobey did not enjoy it at all. I feel that we can do the shots easily but the issue comes with the meter. I purchased the True2Go made by Homediagnostics. The vet's meter showed a reading of 450 but with our meter with the same blood taken by the vet showed 250. I am not sure what to do. Get a new meter? Also do I need a new lancet with every test? Any and all advice would be appreicated. I have not yet purchased more test strips and would like to figure this out before I do. Thank you so much for your help.
