QUALITY ASSURANCE
ANALYZING CELL CONTROLS
b. Make sure the trainee is aware of the following:
1) Open-vial stability is listed according to days or events. An event has occurred
anytime an Operator completes the following sequence:
a) Removes a control vial from the refrigerator
b) Allows the control vial to stand at room temperature 15 minutes
c) Mixes the control vial gently by hand using the 8 x 8 x 8 method two times
d) Aspirates sample
e) Returns the control vial to the refrigerator within 30 minutes
2) The conditions that indicate deterioration:
a) Inability to obtain expected values in the absence of known instrument
problems
b) Gross hemolysis (darkly colored supernatant)
Note: This condition is documented on the assay sheet.
3) The conditions that do not indicate deterioration.
a) A slight pink color to the supernatant is normal.
Note: This condition is documented on the assay sheet.
b) The RBC and PLT parameters may trend over the controls expiration
dating.
4) The control is designed with a pierceable cap so you can run it with the cap on.
a) In the Autoloader mode, you must run the control with the cap on.
b) In the Manual mode, it is recommended that you run the control with the
cap on to prevent spillage and reduce biohazard exposure.
5) Although control levels may be run in any order, Low, Normal, then High
provides the best statistical results.
3. To print a full report of a control’s results, including the parameter results with expected
ranges and parameter histograms, Auto-Print for controls should be enabled.
a. The screen display from which you can manually print a full report is only available
until the next control is analyzed; so if Auto-Print is not enabled it is likely that you
will miss printing a full printout on some of your controls.
b. Determine if the laboratory needs or wants a full report of the control’s results.
c. Selecting the Auto-Print options for non-patient results is covered under
Heading 3.4, SYSTEM SETUP OPTIONS, in this Training Guide.
d. To view the current Auto-Print setting, from the Main Menu click tt tt
Printer tab.
4. Help the trainee locate
Heading 7.3 RUNNING CELL CONTROLS, in the Online Help System or
the Instructions for Use manual.
a. This section covers three procedures for running cell controls:
1) Running Cell Controls: Autoloader Mode With Barcode ID
2) Running Cell Controls: Autoloader Mode Without Barcode ID
3) Running Cell Controls: Manual (Stat) Mode.
