CoaguChek® XS

Further benefits for you and your patients

Each individual reacts differently to oral anticoagulant treatment. Stress, other medications e.g. some pain killers or antibiotics, diets rich in vitamin K (e.g sprout or cabbage) or alcohol, may interfere with oral anti-coagulant therapy (drugs called vitamin K antagonists). Some conditions like fever or diarrhoea might also have an impact on INR results. It is therefore important to check the PT/INR regularly. The Roche CoaguChek XS system gives very fast (1 min) PT/INR results using capillary blood using only one drop from the fingertip.


De CoaguChek XS en het zelfcontrolesysteem bezorgen u meer:

Comfort

• -One drop of capillary whole blood (only 10 µl) to get a quick (1 min) and precise INR result
  
• -Virtually pain-free testing using CoaguChek Softclix lancing device: there is no need for venous blood sampling
  
• -Choice between top-dosing and side-dosing options offers an easier application of blood
  
• -Possibility to test anywhere and anytime: it is easy to transport due to its low weight and size, and practicalities are improved as strips are stable at room temperature (no refrigeration is required)

Safety

You can count on an On-Board-Integrated-System Control (OBIS). It comprises:

• -On-board integrity check of every strip directly in the measuring channel (OS2C system)
  
• -Failsafe features: device and strip are constantly checked during the measuring process e.g. check for sufficient blood volume application
  
• -Automatic control of internal system functions
  Give yourself peace of mind and improve your quality of life with the CoaguChek XS system from Roche Diagnostics!

Put a test strip in the CoaguChek XS

The code number of the code chip inserted in the monitor flashes in the display. Make sure that this number is identical with the code number printed on the test strip container. If the two numbers are identical, confirm by pressing the M button.

Prick the finger of your patient with a lancet device approved for professional use

The blood drop symbol and the application area flash to indicate that the monitor is ready to test. At the same time a 120-second countdown begins. Within this time you must have applied the drop of blood. And...


...place a drop of blood on the strip
Apply the blood directly from the finger to the semicircular, transparent sample application area of the test strip. Apply the blood drop to the test strip within 15 seconds of pricking the fingertip.
Alternatively, you can touch the blood drop against the side of the sample application area (instead of applying it to the centre from above).
After about one minute, read the result on the CoaguChek XS display

 - for these teststrips, a small sample of capillary blood (10µl) will be sufficient.

 

- To avoid contamination, the bloodsample will be applied outside the reader. The bloodsample can be applied on top or on the edge of the strip, which increases usability a lot.

 

- The teststrips can be preserved at room temperature. They keep their stability for 18 months.

 

- The unique technology permits to detect the activity of the thrombin electrochemical by using amperometry. the signal is proportional with thecoalescense time. The CoaguChek XS PT teststrip contains reagents in dry form, the recombinant tissuefactor (tromboplastine ISI~ 1) and a peptidesubstrate (electrocyme TH) that can be used to determine serine  proteases like trombine. When the bloodsample is applied, the tromboplastine activates the coagulation, which forms the trombine. The trombine segregates the electrocyme TH and generates an electrical signal that is proportional with the coalescense time.

 

- thanks to the  specific form of the teststrip, a drop of blood is induced to the strip;  patients will not have any nuisance of the withdrawel of blood or the aplication of the blood sample.

 

- The CoaguChek® XS Plus PT Test teststrip guarantees total safety thanks to the built-in "on-board single channel strip control: OS2C" quality check. This "OS2C"-systeem tracks on a absolute safe way all teststrips that wer not contained in a proper way. besides the reagens for the determination of the coagulation factor, the teststrip contains also the a reagens that detects when a teststrip is not proper used and that is very sensitive to environmental factors like light, humidity and temperature. The measured effect is proportional to the damage of the teststrip.

 

-  Each teststrip is checked in het measuerment channel during the complete measurement process. For instanstance the volume of the bloodsample is checked.

 

-Each container with teststrips is supplied with a chip containing all the data about the testmethod, batch number and expiration date. The chip is unique for a batch lot of teststrips.
