Good morning. I just tested my waking bg and it was 7.9. I thought this was rather high considering i haven't eaten for 10 hours. So I tested again and got 7.6. Ive done 5 consecutive tests and each one has given a different reading ranging from 7.1 to 7.9. Isn't this a quite unreliable? I used the same finger and blood from the same prick hole so how can it vary so much?
