the reading ought to be the same regardless of where you take it...are you using a fresh paper each time...? 4 points is a lot if you are taking readings at the same time.....but it can rise quickly if you eat in between taking blood...
quincy, you really dont need to bother testing your blood sugar levels twice like that.. just once, each time, is enough.
test when you wake, before eating (and then 2 hours later to get a good indication of how different foods affect you) and then test again at bed time.
the difference in 'points' could be that you might have had something sweet on the other finger tip or something, hence the slightly increased reading.
how are your levels by the way, are they ok?
