Quality control
Integrated quality control
The Xprecia Prime™ meter has a number of integrated quality-control
functions:
• A check of components and functions is performed every
time the meter is turned on.
• The barcode information on the strip and vial are read by a
scanner inside the Xprecia Prime™ meter. The meter then
checks:
o the strip’s expiration date and lot information; and
o the strip’s calibration values.
• During the test, the strip’s integrity is monitored. The strip’s
temperature is also controlled to ensure test results are
reproducible.
An error is reported if the meter fails any of the above checks.
Warning and error messages are described in Chapter 8
(Troubleshooting) on page 52.
External quality control
To help your facility comply with regulatory requirements, you can
run a check of the system at any time using the optional Siemens
Xprecia™ Systems PT Controls. This check—called a LQC test—
compares the measurement of a control sample against a pre-
determined acceptable range of readings.
LQC tests are explained in detail in chapter 4.
