If you have already done that then your number should be accurate. I wouldn't place a whole lot of stock in blood sugars before you changed the battery as they may have been off. Start for now and you will be confident. ...Read more

Yes: A meter can give you a false value, especially if it's old. If you get an unexpected result, it's a good idea to check it again before you act on it.
