on the front of the test

be completely blue for
an accurate test.
Not Enough
Blood
Back
If any white patches or
streaks appear on the
blue confirmation dot,
you have not applied
enough blood for an
accurate test. You must
start the test over with
a new test strip to
avoid false low results.

If there is no white
visible on the white
pad, you have applied

must start the test over
with a new test strip to
avoid false high results.

apply too much blood,
especially if you tend
to bleed easily or are
taking blood-thinning
medications.
