You have the option of obtaining a blood sample from other sites on your body besides the fingertip.
Alternate sites include the palm, forearm, and upper arm. The two palm testing sites are the fleshy areas
under the thumb (thenar) and under the little finger (hypothenar). Blood obtained from the fingertip can be
used at any time to test blood glucose. If blood from an alternate site is used, there are certain times when
testing is not appropriate (see next section). This is because your blood glucose level changes faster in your
fingertip than in the alternate sites. These differences may cause you to make the wrong therapeutic
decision, producing adverse health effects. Please read the following section before you test from alternate
sites.
IMPORTANT
Talk to your healthcare professional before you begin using alternate test sites.
