Clinitek Advantus Operator’s Guide 33
Quality Control
4 Quality Control
Run negative and positive controls on a regular basis to check the Siemens
Diagnostics Reagent Strip performance and analyzer operation. Quality control
(QC) testing provides confidence that the reagent strips are reacting and being
read correctly. It can also detect errors resulting from user techniques. Refer to
your laboratory quality assurance program to ensure quality throughout the
entire testing process. Run controls under the following conditions:
• at the start of the day’s run
• when using a new bottle of reagent strips
• whenever test results are in doubt
• when training new operators
The Clinitek Advantus analyzer can prompt for regular QC testing. You can set
the interval between QC tests from 1 hour to 99 days. You can prevent the
analyzer from being used for testing when a QC test is due. Select the QC
interval and requirement through the Setup routine.
Use CHEK-STIX
®
Positive and Negative Control Strips for Urinalysis. The
solutions prepared using the control strips provide positive, negative, or
defined concentrations when used with traditional Siemens Diagnostics
Reagent Strips for Urinalysis. You can also use a urine specimen from a
normal, healthy individual as a negative specimen.
NOTE: When using MULTISTIX PRO Reagent Strips, use commercially
available controls that include values for each test on the strip. CHEK-STIX
Control Strips are not suitable for use with these products.
For information about control manufacturers, contact your local technical
support provider.
