Pick out a piece of scrap wood. Because of a shim's size and function, the type of wood you choose isn't very important. Even out the edges of your scrap piece of wood by cutting around it with your jigsaw. A shim can be as wide or long as needed.
Monitoring measures your blood glucose at a moment in time, whereas eAG/A1C represent an average of your glucose levels 24 hours a day, including times when people are less likely to check their blood glucose (for example, post-meal periods of higher blood glucose).
Figure 1 below shows a meter with a 14-day average of 106 mg/dL. Let's say that the person in this example also has an A1c level that is 7.9%. That usually reflects a 2-3 month blood glucose average of 180 mg/dL.
