Abbott i-STAT Alinity, Operation Manual, Page: 112 / 296

Electronic value assignment sheets (eVAS or ReVAS) may be downloaded to a customized instrument via
the Abbott Managed Server, the SDi, or USB. See the System Operations Manual for information and
instruction on creating customization profiles. Selection of eVAS or ReVAS must be made during the
creation of the profile.
Note: Follow facility policy regarding control results that do not fall within assigned
ranges.
Disposal
Check with authorities for local, state, and/or national requirements for disposal.
Procedure for Testing
Prerequisites
•
Ampules, cartridges, and instruments must be at the same temperature.
•
Controls solutions require different temperature stabilization times depending on whether PO
2
is to
be measured. If PO
2
is to be measured, equilibrate the ampule for 4 hours. If not, equilibrate the
ampule for approximately 30 minutes at room (ambient) temperature.
•
Do not use the solution left in a syringe, ampule or capillary tube for additional testing of cartridges
that contain sensors for iCa, pH, PCO
2
or PO
2
. However, cartridges without these sensors may be
tested with remaining fluids if within 10 minutes of opening the ampule.
•
Since aqueous based solutions such as controls lack the buffering capabilities of whole blood, the
transfer process from ampule to cartridge must be more expedient than with a patient sample.
Performing Quality Control Testing
1. Press Power and allow instrument to power on.
Note: After powering on the instrument, one or more alert messages may display.
Read the message carefully and perform the functions necessary to evaluate and/or
clear the alert. The Home screen will display when the alerts have been successfully
managed.
2. From the Home screen touch More Options > Quality Options > Quality Control. Select the button
that is appropriate for the testing. Continue to follow the prompts on the screen. There are three
pathways available for performing liquid QC tests. The default is unscheduled. The other two options
are available when the instrument is customized by the system administrator (see the Customization
Workspace for i
‑
STAT (AlinIQ CWi)).
3. Enter the required information by following the prompts on the screen. Prepare the cartridge and
control solution for testing.
4. Shake the ampule vigorously for 5 to 10 seconds to equilibrate the liquid and gas phases. To shake,
hold the ampule at the tip and bottom with forefinger and thumb to minimize increasing the
temperature of the solution. If necessary, tap the tip of the ampule to send solution back into the
bottom section of the ampule.
5. Protect fingers with gauze, tissue or glove, or use an ampule breaker to snap off the tip of the ampule
at the neck.
6. Immediately transfer the solution from the ampule into a capillary tube or syringe (refer to
information for transferring the control solution, below), and then immediately transfer the solution
into a cartridge. Help graphics on the instrument show the transfer of control material to the
cartridge via a syringe with a blunt tip needle.
