Testing a Blood Sample
Do not use forearm testing:
• For at least 2 hours after you have eaten or injected insulin
• If you have recently exercised
• If you think that your blood glucose is low
• If you think that your blood glucose may be changing rapidly
(e.g., after a meal, after taking insulin, or during or after exercise)
• If you are not aware of symptoms when your blood glucose is
low (hypoglycemic)
• If your forearm test results do not match the way you feel,
retest using your finger or palm.
Consider
NOT
using forearm testing if you:
• Are ill
• Are under extra stress
• Routinely have widely fluctuating blood glucose values that
are often low (hypoglycemic)
Values from the palm sample were shown to be equivalent to
values from the finger samples.
