As part of the re-calibration of our test strips to the new World Health Organisation (WHO) preparation standard performed in January 2018, we found that test strips with certain lot numbers have shown higher than expected variance at INR values of greater than 4.5.
All CoaguChek users, both healthcare professionals and patients, in UK and Ireland with the affected test strips have been contacted and are to expect to receive a letter.
For those who may not be affected, or wish to know specific details, please visit the information held on CoaguChek.co.uk along with contact details for a team dedicated to supporting you.
