Alternate site testing


When testing alternate sites, use the ACCU-CHEK FastClix lancing device—proven least painful and overall easiest to use.4

Some blood glucose meters allow you to use a blood sample from non-fingertip (alternate) sites such as the palm, forearm or upper arm.1 Because the skin of these areas contains fewer nerves than the fingertip, alternate site testing may be more comfortable.2

It's important to know that while blood from your fingertip can be tested at any time, there are times when alternate site testing may not give you the most accurate result.

When it's okay—and not okay—to check from alternate sites(3)

Alternate site testing should only be used when blood sugar is stable:

  • Immediately before a meal
  • When fasting
  • Near bedtime

Always check from your fingertip, however, when blood sugar may be changing:

  • Following a meal, when blood sugar is rising quickly
  • After exercise
  • Whenever you think your blood sugar might be low or falling

Important alternate site testing notes

If you're considering alternate site glucose testing, please remember:

  • Never ignore the symptoms of low or high blood sugar.
  • If the results of a blood glucose test don't match the way you feel, confirm with a fingertip test. If the fingertip result still doesn't seem to reflect the way you feel, get in touch with your healthcare professional.
  • Please talk to your healthcare professional before using sites other than your fingertip for testing blood sugar.
