Quality Control
Overview
The purpose of quality control (QC) is to verify the integrity of your slides and also to verify that your
Catalyst One* analyzer is functioning properly.
You should run a QC test:
• When the analyzer is first installed.
• After cleaning the internal components of the analyzer.
• If the analyzer has been moved.
• To verify system performance.
Quality Control Materials
IDEXX VetTrol
*
Control
In each box of IDEXX VetTrol* Control, there are four vials containing freeze-dried powder (dark
brown bottle marked “VetTrol Control”) and four vials containing diluent (lighter bottles marked
“Diluent for VetTrol”). The lot numbers for the diluent and the control are different and can be found
on the product packaging.
For more information about IDEXX VetTrol Control, see its package insert.
Storage
Control and diluent vials should be stored frozen (-18°C/0°F). Discard opened control vials
within 24 hours. Expired or unwanted material should be discarded with other clinical waste.
Note:
Do not store in the freezer door; only in the main freezer compartment.
Stability and Handling
For most chemistries, IDEXX VetTrol Control can be used up to 24 hours after reconstitution
when it is stored in the refrigerator and equilibrated to room temperature before running (do not
leave at room temperature for more than 2 hours). For creatine kinase and ammonia values,
IDEXX VetTrol Control fluid should be used within 2 hours following reconstitution. Exposure to
light will affect total bilirubin and creatine kinase results. Ammonia concentration will increase
with time.
UPRO Control
In each box of UPRO Control, there are six vials containing the control fluid. The lot number can be
found on the product packaging.
Storage
Control fluid should be refrigerated (2°C–8°C/36°F–46°F). Discard at the expiration date.
Expired or unwanted material should be discarded with other clinical waste.
Stability and Handling
Use within 24 hours after opening (refrigerate when not in use).
