@@Avandamet Welcome to the group and Welcome to the wonderful world of testing your blood sugar.

For most of us, it is rare that we get the same reading even if we test withing seconds of the first test. Here are some things that may affect your readings.

- One test may have picked up a contaminant from the skin that affected the reading. It is important to wash and dry your hands before testing. I've forgotten to wash my hands and gotten readings 100 points higher than it really was. I have also see advice to wipe the first drop of blood off with a sterile pad then squeeze out a second drop. This also helps clear away contaminates. I can never get the second drop, so I don't know if it helps. Speaking of squeezing out a drop, I've see the recommendation not to squeeze, but I would never get any blood.

- The meters are not as accurate as we would expect. It is my understanding that they are most accurate near the "normal" blood sugar range and get less accurate the higher the concentration of sugar in the blood. I ranted to a type 1 friend that I sometimes thought the meter was a random number generator. He replied that there is some truth to that. Unfortunately, there is not a lot of good information as to what meters are best.

This is an article from 2010, "Currently, most available blood glucose meters are accurate only to within 10% to 15% of the actual blood glucose level." I do not think tighter standards have been implemented. The numbers you are stating would be in the range of error allowed for meters.

- You did not say how long after a meal you took your first test, but it may be that the meal previous to your first test is pumping some sugars into your system. Wait two hours after you eat before testing.

- Stress can also affect levels. It sounds like you may be stressing over the first reading, possibly affecting the second.

Hope this helps. Unless the test is way out of the range expected (based on experience) I just record the test and move on.

About squeezing out a drop ... I know it hurts more, but if you crank your (not sure what to call it, but the thing with the lancet in it that pokes your finger) to a higher number, you will get a bigger drop of blood ...

Have found that even if you check your numbers within a minute - readings will be different every time, doesn't matter if it's a minute, half hour hour or an hour
