Something that bears the brunt of many jokes in the diabetes community is the test strip. If you haven't a clue what that is. No worries, I'll explain. The test strip is a very small yet essential item for anyone living with diabetes. In order to keep blood glucose levels in check you have to take regular measurements with a blood sugar measuring device called a glucometer. Even if I wear a CGM (continuous blood glucose monitor) which measures blood sugar through an implanted device, I still need to calibrate my CGM or double check that the reading I'm getting is accurate. Especially in an emergency. Nothing worse than getting a false reading on my CGM and treating it with either insulin or glucose and then having either a low or high. Sound complicated? Not even the half of it.
