Alternative Site Testing
What is AST(Alternative 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 arms, 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 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. Gently massage the
sample site 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.
Alternative Sites for Testing
Things To Know When Using AST
Please read the following before testing at alternative sites
(forearms, palms, thighs, and calves).
The capillary whole blood of the fingertips reflects changes in
glucose levels more rapidly than in alternative sites. The test
results from the fingertip testing and AST may differ due to
factors such as lifestyle and ingested food which affect glucose
levels.
Acceptable Situations for AST
When your blood glucose levels are stable
• Fasting period
• Before a meal
• Before going to bed
Situations Requiring Fingertip Test
When your blood glucose levels are unstable
• During the two (2) hours after a meal or exercise
• When sick or when glucose levels seem quite lower than
test value
• When hypoglycemia is not well recognized
• When insulin has the biggest effect
• During two (2) hours after an insulin injection
