Error: Sample Error
Measurement error
caused by the blood
sample.
Solution:
If you see “error 7,” this
means the meter was
unable to detect a clot.
Repeat the test. Be sure to
carefully follow the steps
on the previous pages. For
example, make sure the
fingertip is thoroughly dry,
use the meter on a surface
free of vibrations, and
apply the blood drop
within 15 seconds of
sticking the fingertip. If you
still get “error 7,” call your
doctor immediately to
arrange for testing using
another method.
This error message (7) can occur in rare cases, i.e.
in patients with unusually long coagulation times
(> 10 INR). If this error message appears again when
the test is repeated, it’s urgent to contact a doctor
immediately and seek an alternate method of testing!
