How the System Works

The CoaguChek XS System includes a meter and
CoaguChek XS PT test strips. Each box of test strips has
its own code chip that you insert into the meter. The
code chip contains important information about the test
strips such as their expiration date and lot number.
The CoaguChek XS System makes measuring blood-
clotting time easy. The display on the meter guides
you through the testing process. With the code chip
inserted in the meter, you simply insert a test strip and
apply a blood sample when the meter is ready. The
meter displays the result in about a minute. The meter
automatically stores the result in memory so that you
can easily recall results.
The CoaguChek XS PT test strip contains various
ingredients. When a blood drop is applied, the meter
starts the test and the blood mixes with the ingredients
on the test strip. When the meter determines that
the blood has clotted, it stops the measurement and
calculates the result.
