ALTERNATIVE SITE TESTING (AST)
What Is Alternate Site Testing?
Alternative site testing (AST) is the use of parts of the body,
other than the fingertips, to check blood glucose levels. The
Glucose Monitoring System allows you to test on the palm,
forearm, upper arm, calf, or thigh with equivalent results to
fingertip testing when used at appropriate times.
There are limitations for doing AST. Please consult your
healthcare professional before you conduct AST. The Glucose
Monitoring System should only be used for AST under steady-
state blood glucose conditions.
What Is the Advantage of Alternative Site Testing?
Pain is felt more readily on the fingertips because they are full
of nerve endings (receptors). At other body sites where nerve
endings are not so condensed, pain is not felt as acutely.
When Should You Use Alternative Site Testing?
Food, medication, illness, stress, and exercise can affect blood glucose levels. Capillary blood from the
fingertips reflects these changes faster than capillary blood from other sites. Therefore, when testing
blood glucose levels during or immediately after meals exercise, or when another of the above-noted
conditions applies, take a blood sample from your fingertips only. AST should be used only during steady
–
state times when glucose levels is not changing rapidly.
Blood glucose results from the forearm, upper arm, hand, thigh and calf are not always the same as
results from fingertips. Alternative Site Testing is suitable in the following instances:
•
In a pre-meal or fasting state (two hours or more after the last meal)
•
Two hours or more after taking insulin
•
Two hours or more after exercising
Caution: Do not use sites other than fingertips for testing when blood glucose is rapidly rising or falling,
within 2 hours of eating, after taking insulin, immediately after exercise, or when you are ill or under
stress. Alternative Site Testing should not be used to calibrate continuous glucose monitoring systems
(CGMs). Results from Alternative Site Testing should not be used in insulin dose calculations. Do not use
AST if:
•
You think your blood glucose is low
•
You are unaware that you might have hypoglycemia
•
You are testing for hyperglycemia
•
Your AST results do not match the way you feel
•
Your routine glucose results fluctuate often
