Roche has confirmed the potential for an undetected elevated INR test result with the CoaguChek XS, CoaguChek XS Plus, and CoaguChek XS Pro meters. In rare cases, instead of a value, an “ERROR 6” message is displayed.

“ERROR 6” messages are generally due to an activation of the system fail-safe mechanisms that are designed to prevent the release of wrong measurement results.

However, patients who are under treatment with Warfarin in combination with antibiotics and/or chemotherapeutics, which could potentially lead to extremely high coagulation times (> 10 INR), may in rare cases receive repeated “ERROR 6” messages instead of an INR value.
