Alternate Site Testing
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 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 0.5
μ
L, actual size: ) blood is drawn.
Carefully lift the lancing device away from your skin.
Before using AST, please consult your healthcare professional.
Step 1
Unscrew the lancing device tip.
Step 2
Stick the lancet into the saved
protective disk.
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.
