I have a situation here and I hope all of you can help me. My mother was diagnosed with pre-diabetes with a fasting glucose of 106 (we are in the US). I became concerned because my mothers diet is much better than mine. I bought a glucometer One Touch Ultra 2 and tested my glucose level that same morning. It came out at 112. I cut on calories thinking that was the problem and limited my diet to 1600 calories per day... three days later and it marked 114. The I came to learn that it was carbohydrates the one I should be taking care of and started a 10 carbs per meal for about 4 or five days. Then I was told that the glucometers are not very accurate and that I should be tested in a lab. I started to eat 160 carbs per day... 40 per meal before for 4 days and went to get tested. Results came back as 93. I tested next morning with glucometer and it marked 87. Yesterday I tested fasting and got 100. later that day I tested after taking a 30 carbs meal and my number were 147 at the one hour mark and 112 at the two hour mark. So my concern is that my numbers were a little high I think for a 30 carb meal and that lab test came back as normal because I was making diet for about a week and a half prior. Should I trust my lab result and assume I am ok or should I trust my glucometer and seek further help?
