Once the needle has pricked the finger, a small drop of blood is placed on the end of the test strip, and the meter quickly provides a reading of the person's current blood sugar level, explains American Diabetes Association.

For example, some meters allow for blood samples from other areas of the body, such as the thighs, forearms or hand flesh. The needles come in manual and spring-loaded designs, but the latter are much less painful and easier to use.
