CoaguChek® XS System

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 meter and test strips work together to
provide a safe and reliable system for testing blood-clotting time.
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. 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.
