The CoaguChek XS system is a compact, convenient and precise device which allows patients on oral anticoagulation therapy who have to regularly monitor their PT/INR results to experience a significant improvement in life quality through increased involvement in the management of their condition. The CoaguChek XS system encompasses several innovative enhancements which offer more security and confidence with getting fast PT/INR results. Customer benefits With the CoaguChek XS system and coagulation self-monitoring, patients will benefit from more: 1- Comfort by virtually pain-free testing, anywhere and anytime: Virtually pain-free testing using the CoaguChek Softclix lancing device: no need for venous blood sampling. Only one drop of capillary whole blood (10 µl) from the fingertip to get a quick (1 min) and precise INR result. Choice between top-dosing and 2 side-dosing options offers an easier application of blood. Room temperature stability for strips improves logistics … 2- Safety by counting on an On-Board-Integrated-System Control (OBIS): Displays results only after several quality control steps have been passed. Automatic control of internal system functions. On-board single-channel strip control (OS2C) which checks the integrity of every strip directly in the measuring channel. Failsafe features: device and strip are constantly monitored during the measuring process (e.g. check for sufficient blood volume application).
