It depends on what is was before. My first reading on my Accu-Chek Mobile meter was 9.8, but previously my blood sugar was 13.1, so that was good. I found that the readings dropped over the next few weeks to 8, 7 and are now around 6.3.
If you keep with a low carb diet, it should get better over time. Normal fasting blood sugar readings for type 2 should be in the range 4-7, so 7.7 is not far off that.
