Wash your hands with soap and
warm water and dry them thor-
oughly. Warm water stimulates
blood flow to the fingers. Hang
your arm down for 10–15 seconds

use alcohol to clean your finger,
make sure you let it dry.
To avoid soreness, choose a site on
the side of your fingertips. To avoid
calluses, choose a different spot each
time you test.
