6 Control Testing and Quality Control
The CoaguChek XS Pro meter has a number of built-in quality control functions.
■ A check of the electronic components and functions 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.
■ A two-level, onboard quality control test and patient result determination within a single
test chamber.
Roche offers optional liquid quality controls for the CoaguChek XS Pro system. These controls
are provided to assist with regulatory compliance requirements as applicable to your facility.
To perform an optional liquid quality control test using control solutions, you need:
■ CoaguChek XS Pro 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 XS PT Controls (not available in the United States) or
CoaguChek XS Pro PT 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 72). If the control
results in the display are in the specified range, this confirms that the liquid control test was
performed correctly.
