I don't have the big D but was interested to do some tests on myself. All of my results were under 5.9 mmol/L before meals and under 7.8 mmol/L after meals. However, I noted:
1) If the blood was smeared in the meter could say "too low to measure"
2) The second drop generally gives a different result to the first, sometimes notable. At the higher range a couple of hours after a sugar orgy I think the readings where 6.4 and 7 from the same sample
