5 Control and Proficiency Testing
5.1 Control testing
The CoaguChek Pro II meter has a number of built-in
quality control functions.
■ A check of the electronic components and func-
tions every time the meter is powered on.
■ A check of the test strip temperature while a test is
in progress.
■ A check of the expiration date and lot information
on the test strip carried out by the code chip.
■ An onboard quality control within every single test
strip.
Roche Diagnostics offers liquid quality controls for the
CoaguChek Pro II system. These controls are designed to
assist you in meeting regulatory compliance require-
ments at your facility.
To perform an optional liquid quality control test using
control solutions, you need:
■ CoaguChek Pro II meter
■ The test strip code chip supplied with the test strip
container you are using (a code chip is provided
with every test strip pack).
■ Test strips that came with the code chip mentioned
above
■ Bottles of CoaguChek PT Controls, CoaguChek
aPTT Controls, diluent droppers, and the quality
control code chip provided.
You can choose the frequency of liquid quality control
tests in the meter setup. (Refer to the chapter entitled
“Meter Setup”/“QC (quality control) Lockout” starting on
page 83). If the control results in the display are in the
specified range, this confirms that the liquid control test
was performed correctly.
