CoaguChek^{^®} XS system

Coagulation self-testing made easy

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.

The support you need. If you or your patients have questions, live technical support is available by phone.
