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.
For meters with serial number UP0910000 and
lower: In rare cases, “error 6” may indicate
extremely high coagulation times (> 10 INR). If
“error 6” is displayed repeatedly, please contact your
doctor without delay.
