E-406: Sample Error Error message
Touch to exit this message. Perform the
suggested step(s) to solve the problem.
Power the meter off and remove the test strip. Repeat
the measurement using a new test strip and blood
taken from a new puncture site at the tip of another
finger. Do not touch or remove the test strip when a
test is in progress.
Note on error E‑406: The CoaguChek PT Test strip
may be used for patients under a combination therapy
of oral anticoagulants plus heparin injections. For
maximum heparin concentrations which do not
interfere with the test, refer to the package insert. In
rare cases, patients with abnormal or unusually long
clotting times may receive an “E‑406” message on the
meter display. This may occur, for example, during
treatment with vitamin K antagonists in combination
with antibiotics, chemotherapeutics, or extremely high
levels of vitamin C (e.g. after vitamin C infusions).
