For the greatest reduction in pain, lance on the sides of
the fingertips. Rotation of sites is recommended.
Repeated punctures in the same spot can make your
fingers sore and callused.
Forearm and Palm Testing
The forearm and palm areas have less nerve endings than the fingertip. Because
of this, you may find that obtaining blood from these sites is less painful than from
the fingertip. The procedure for forearm and palm sampling is different. You need
the clear cap to draw blood from these sites. The clear cap is not adjustable for
puncture depth.
IMPORTANT:
There are important differences among forearm, palm and fingertip
samples that you should know. Important Information about forearm and palm
glucose testing:
•
You should consult your doctor before choosing to perform forearm or palm
testing.
•
When blood levels are changing rapidly, such as after a meal, insulin dose or
exercise, blood from the fingertips may show these changes more rapidly than
blood from other areas.
•
You should use fingertips if testing is within 2 hours of a meal, insulin dose or
exercise. You should also use fingertip testing any time you feel glucose levels
are changing rapidly.
•
You should test with the fingertips anytime there is a concern for hypoglycemia
or you suffer from hypoglycemia unawareness.
•
Alternative site testing (AST) should not be used to calibrate continuous glucose
monitors (CGMs) nor for use in insulin dose calculations.
