The Coaguchek Xs System; Anticoagulation Medication; Blood-Clotting Time - Roche CoaguChek XS System User Manual

The CoaguChek XS System

The CoaguChek XS System measures blood-clotting
time (Prothrombin Time) for people who are taking
anticoagulation medications such as Coumadin
warfarin. The CoaguChek XS System measures blood-
clotting time using blood from the fingertip.

Anticoagulation Medication

Anticoagulation medications, also known as blood
thinners, are prescribed to avoid unwanted clots. Your
blood-clotting time must be monitored to ensure that
your medication dosage is correct.

Blood-clotting Time

The rate at which blood clots is measured in units
called INR. It is very important that you stay within
your target INR range. If your INR is too low, the risk of
blood clots increases. If your INR is too high, the risk
for internal bleeding increases.
Everyone's INR is different. Your doctor determines
the best INR range for you, depending on why you are
taking anticoagulants and how you react to them. Your
doctor also determines how often your blood should be
tested. Your doctor needs to know your blood-clotting
time in order to successfully treat you.
