CoaguChek® systems

    The smart way to test INR at the Point of Need

CoaguChek® XS Plus


CoaguChek® XS Plus provides accuracy, ease of use plus data management for recording patient IDs


PT/INR Monitoring tailored to a healthcare professional’s needs. 

Test your patients’ PT/INR right in your practice instead of waiting for lab results.

All three CoaguChek XS devices use the same testing technology.  So the CoaguChek XS Plus and Pro produce results equivalent to those obtained with reference laboratory methods and also compare closely to the patient’s device, the CoaguChek XS.

Accurate and flexible technology – a smart way to test

  • Accurate, precise results in about one minute
  • The only system to perform onboard quality control and patient tests in a single test chamber
  • Results unaffected by heparin at therapeutic  levels
  • INR corrected for hematocrit within specified range

Streamlined data management

  • Stores 2000 patient and 500 QC test results
  • Operator and QC  lockout to ensure your policies are followed
  • Calibration via code chip
  • Stores lot data for up to 60 codes
