Do I Have to Prick My Skin to Test My Blood Glucose?

Read Transcript

The continuous glucose monitors are devices that you wear where there is a plastic [xx] that's inserted through the skin, and stays in place for about a week, and it measures the glucose level and the fluid that is in between the fat cells, which is not the same as blood sugar, but it's in close equilibrium with blood sugar.

So it changes as the blood sugar changes, and will give you some information about what's happening to your sugar, but when you say it's not always a pin prick or a finger stick that brings up another issue which is there's an awful lot of misleading advertising out there. When you hear an advertisement say, no finger sticks, or you don't have to prick your finger, it's kind of misleading because you still have to break the skin to get a drop of blood from somewhere, and they're simply saying that you don't necessarily have to use your finger stick.

But actually I tell people that the least uncomfortable way to get a blood sugar reading is to use your finger tip and just do it properly. So what I usually say is to put the hand down with the palm side up on a flat surface like a table top to press the lancing device firmly into the finger tip to stretch the skin and then release the lancet that stretches the skin out tight like a drum that lancet hardly has to pierce the skin to get a drop of blood.
