How do I get a blood sample for a glucose reading?

Dr. Jack Merendino, MD

The finger is usually where you collect your blood sample. If you do it right, you'll feel just a little pressure but no pain. Here's the technique: Place your hand on a firm surface such as a tabletop with your palm facing up. This will prevent you from unconsciously pulling away as you are about to stick your finger. Dial the lancet device -- a penlike instrument containing a lancet, a sharp, disposable needle -- to the lowest level (with the least penetration). Push the lancet device firmly into your finger, stretching the skin tight like a drum. This will allow it to pierce your skin without going very deep, and the pressure will push up a drop of blood. Many people have told us that this method causes them almost no pain. If the lowest setting doesn't pierce the skin, try the next to lowest, and so on.
