Point-of-Care PT/INR testing made easier
 

With the CLIA waived CoaguChek XS system, accuracy and convenience are right at hand. This small, handheld, battery-powered meter is ideal for low- to mid-volume office settings. Plus, you can test and treat in one appointment using the fingerstick test that patients prefer.1 In fact, more INR tests are performed in the United States with the CoaguChek XS meter than all other INR meters combined.2
 

Designed for comfort, convenience and easy reporting:
 

Easy to use. The CoaguChek XS meter features two-button operation, automatic power-on and a large, easy-to-read display. Just one drop of blood is applied to the test strip to measure clotting time.

Fast results. The CoaguChek XS displays INR results in about a minute.

24/7 support. If you or your patients have questions, live technical support is always available by phone.

I feel like I got my passport back.

 

The CoaguChek XS system is ready for use anywhere at any time. Patients can use it for self-monitoring at home or while on vacation.

 

Fast, reliable results

 

  • Accurate PT/INR results in one minute
  • Built-in quality control checks every strip automatically
  • Lab-comparable accuracy1

 

Simple fingerstick test

 

  • Most patients prefer having a small drop of blood (just 8 μL) taken from a fingerstick to having blood drawn from a vein3

 

Improved patient outcomes

 

  • Patients who self test have been shown to spend more time in therapeutic range and have less thrombembolic events2

Detection system

 

Amperometric (electrochemical) determination of the PT time after activation of the coagulation with human recombinant thromboplastin

  • User interface: Icon-based LCD display; on/off, mem and set buttons

 

Measuring range

 

INR: 0.8 - 8.0

%Quick: 120 - 5

Seconds: 9.6 - 96
