How deep should I set the lancing device of my blood sugar meter?

William Lee Dubois
Endocrinology Diabetes & Metabolism
Once you poke a hole in your finger, a very gentle squeeze should bring the blood to the surface. If you have to milk your finger like a cow you need a deeper or larger diameter hole. Lots of pumping of the finger mixes interstitial fluid (water between cells) into the blood sample and will throw off your results.

If it hurts to lance your finger, you probably have your device set too deeply or you put the clear cap on the lance. Yeah, that’s for testing on your forearm. Throw the clear cap away and put the solid one on. For what it is worth, there are some folks out there who really do have hypersensitive fingers. For you folks there are two pretty expensive solutions: a computerized lancing device that lets you micro-control hundreds of different depths; and a laser that burns a painless hole in your skin.
