The CoaguChek® XS system is ready to use anywhere, any time. You can test yourself at home, school, work or on vacation.

Fast, reliable results

  • Accurate PT/INR results in one minute
  • Built-in quality control checks each and every strip automatically

Simple fingerstick test

Most patients prefer having a small drop of blood (just 8 μL) taken from a fingerstick over having blood drawn from a vein

Improved patient outcomes

Frequent testing leads to fewer life threatening events1 and increases your quality of life.1
