4.2 Preparing to test
1 Have the test strip container at hand.
2 Make sure that the code chip supplied with these
test strips is at hand.
Test strip code chip The code chip provides the meter with important infor-
mation that it needs to perform the coagulation test. The
chip contains information about the test method, the lot
number, and the expiration date. The code chip is
required, whenever a new test strip lot is used, so that the
meter can read and store the lot information about that
particular lot of test strips.
The CoaguChek Pro II meter stores the data from up to 60
test strip code chips that have been inserted.
■ Do not forget to use the test strip code chip that is
supplied with each pack of test strips before you
perform the first test with these strips. We recom-
mend that you leave the code chip in the meter to
protect the electrical contacts in the meter from
becoming dirty.
■ Each code chip belongs to a particular lot of test
strips. Only remove the code chip when you are
testing with test strips taken from a new pack.
■ Protect the code chip from moisture and equipment
that produces magnetic fields.
Each box of test strips (PT, aPTT) contains a code chip.
The parameter, the number on the code chip and the
number on the test strip container must match.
A capital S in front of the number indicates that this
code chip is for test strips. (A capital C in front of the
number indicates that it is a control solution code chip.
