Here is what patient self-testers should know about the recent recall of CoaguChek XS PT Test strips. To see Roche Diagnostics' latest media release addressing this recall, click here.

What Happened?

Roche Diagnostics, the manufacturer of CoaguChek meters and test strips, recently calibrated the CoaguChek test strips to provide INR test results that correspond to the latest industry standards. Since this calibration, Roche Diagnostics has been informed of patients experiencing inaccurately high INR test results when testing with the affected CoaguChek test strips. As a result, Roche Diagnostics issued an Urgent Medical Device Correction (UMDC) in September 2018 instructing users to confirm any CoaguChek test results above an INR of 4.5 with another testing method. You may have received a copy of this UMDC in the mail from your test strip supplier.

Roche Diagnostics is now recalling affected CoaguChek XS PT test strips and shipping new lots of CoaguChek XS PT test strips which are not affected by the recall and which do not require testing with another method. We intend to replace all CoaguChek XS PT Test strips affected by the recall with the new unaffected test strips.
