Performing an Alternate Site Test (AST)
1. Unscrew the adjustable depth cap and replace with the clear cap.
2. Prepare lancing device for testing
3. Select a puncture site from a fleshy area on the forearm. Rub vigorously until it feels
warm. Avoid veins, hair, moles, bones and tendons (see Figure 3-10).
4. Press the clear endcap firmly against the puncture site to create suction and then press
the gray release button. Maintain steady pressure until the drop under the endcap
reaches appropriate size (see Figure 3-11).
5. Lift the device straight up and away from skin without smearing the blood drop (see
Figure 3-12).
6. Apply the blood to the glucose test strip within 20 seconds of puncture (see Figure 3-13).
Do not test the blood sample if you get:
● Smeared blood
● Runny blood
● Clotted blood
● Clear fluid mixed with the blood
7. Wipe the puncture site with a clean, dry tissue and maintain pressure on the site until
the bleeding stops (see Figure 3-14).
