• CoaguChek XS® systems

    The smart way to test INR at the Point of Need

CoaguChek® XS Pro


PT/INR Monitoring tailored to hospital point of care testing

  • Barcode reader for faster ID entry
  • Time critical INR results - faster than sending them to the lab
  • Electronic data capture and transmission aid compliance with accreditation and regulatory standards such as JCI and CLIA '88.

Greater Convenience

Healthcare professionals can measure PT/INR values in approximately 1 minute with a drop of capillary blood (8 µL).

In order to ensure compliance and improve workflows, the system allows patient and operator ID identification with its integrated barcode scanner. Connecting the instrument to the institution’s data management system finally assures safe and efficient patient management

On-the-spot results, no venous sampling

Easy portability; side and top blood dosing options with a capillary sample

Greater Safety

Onboard quality control (QC) for each strip; optional QC lockout to meet potential regulatory requirements; consistent INR results

Greater Workflow Efficiency

Positive patient and/or operator identification, extensive data management and connectivity options.

What is the recommended test frequency?

At least twice per month, preferably once per week. This has proven to increase TTR by enabling faster reactions to variations in INR due to exercise and diet. It also increases patient compliance and engagement. (1,2,3)

What is time in therapeutic range (TTR)?

The percentage of time that your patient’s INR values fell within the upper and lower target value set by you.

Do the CoaguChek XS Pro systems need calibration?

Calibration is performed automatically upon inserting the code key from the strip vial.

What steps can I take when the readings are different to the hospital lab?

Due to diverse measurement standards used by labs, small variations should be expected.  If the variation is of therapeutic significance, please contact your support team at Roche Diagnostics NZ on 0508 69 5433.

Are there interferences when testing with CoaguChek systems?

Polyglobulism: Hematocrit outside the standard range (25 - 55%)
Lupus anticoagulant: INR abnormally high

The presence of anti-phospholipid antibodies (APAs) such as Lupus antibodies (LA) can potentially lead to prolonged clotting times, i.e. elevated INR values. A comparison to an APA-insensitive laboratory method is recommended if the presence of APAs is known or suspected.

Does the user have to run the test immediately after taking the strip out of the vial?

The open vial stability is 10 minutes maximum. Having the strip too long out of the vial, especially in situations with high humidity or temperature, would be detected by the onboard integrity system resulting in an error message. No INR would be displayed if the strips are found to be defective by the integrated quality control of the CoaguChek XS system.

What happens if the user does not change the code key?

If the incorrect code key is in the machine and you insert a test strip, a display message indicates that you need to insert the corresponding code key, otherwise a measurement will not be possible 

How does the underdosing detection work?

The fill of the capillary is detected by a current flow between two electrodes on the test strip. If the capillary is not completely filled an error message (error number 5) will appear on the display.

Is re-dosing possible if the first attempt to get enough blood was unsuccessful?

Yes, re-dosing is possible within 15 seconds. However, in principle re-dosing is very critical due to the immediate start of the coagulation process. Therefore this should be avoided if possible.

What happens if the operator applies blood before the test strip symbol and flashing drop of blood?

An error message  will appear on the screen
