Alternative Site Testing
What is AST (Alternative Site Testing)?
Usually, when someone tests their glucose, they take the
blood sample from the tip of the finger. However, since there
are many nerve endings distributed there, it is quite painful.
When doing a glucose test, using different parts of the body
such as the forearms, palms, thighs, and calves can reduce
the pain during testing. This method of testing with different
parts of the body is called Alternative Site Testing. While AST
may reduce the pain during testing, it may not be simple for
everyone and the following precautions should be observed
during testing.
Alternative Sites for Testing
Alternative Site Blood Sampling (forearm, palm, thigh, calf)
Select a clean, soft and fleshy sample site area free of visible
veins and hair and away from bones. Wash the area with soap
and water and dry thoroughly. Gently massage the sample
with clean hands to help blood circulation to minimize result
differences between fingertip and alternative site sampling.
Firmly press and hold the lancing device against site. Wait
until the skin surface under the lancing device changes color.
Then press the release button while continuing to apply
pressure. Keep holding the lancing device against your skin
until sufficient (at least 0.5 μL, actual size: ) blood is drawn.
Carefully lift the lancing device away from your skin.
Step 1
Unscrew lancing device tip.
Step 2
Place protective cover on lancet. Push
the lancet ejector forward with the
thumb to dispose of the used lancet in
a proper biohazard container.
Discarding Used Lancets
Caution:
The lancet is for single use only. Never share or reuse
a lancet. Always dispose of lancets properly.
