Before using AST, please consult your healthcare professional.
Alternate Site Testing (for glucose only)
What is AST (Alternate Site Testing)?
Usually, we take the blood sample from the tip of the finger.
However, since there are many nerve endings in the fingertip, it
can be quite painful. When doing a glucose test, using different
parts of the body such as the forearms and palms can reduce the
pain during testing. This method of testing with different parts of
the body is called Alternate Site Testing. While AST may reduce
the pain during testing, it may not be simple for everyone and
you should not use AST for your blood β -ketone test. The
following precautions should be observed during testing.
Alternate Sites for Testing
Alternate Site Blood Sampling (forearm and palm)
Select a clean, soft and fleshy sample site area free of visible
veins and hair and away from bones. Gently massage the sample
site to help blood circulation to minimise result differences
between fingertip and alternate 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 0.4 μL,
actual size: ) blood is drawn. Carefully lift the lancing device
away from your skin.
