Couple Day's ago,I called the Company who manufacturers the Meter I've used since early August 2008 and asked for a new Meter.I received it Yesterday.When I checked my BS,it was 90..I quickly rechecked on the old Meter,and it was 131!It is so very important to keep check for malfunction (s) on Meters.
Test Control Solution needs to be discarded 3 Month's after opening regardless expiration Date.Mine expires 05/2010,yet I've used since August 2008..
