I just took 2 blood tests, one immediately the other. Using the same meter, test strips from the same container. and the same hole in my finger, the results were 152 and 137. Most likely number is probably in the middle. I’m not worrying about it. If I were to take insulin based on those numbers, I would have let it go at the first and take insulin based on that number.
The most important thing is something your number agree on. They indicate that your blood sugar is just a bit high, but not too much. Again, your number were 146, 166,128, & 127.
