Resolution
1) Discard the sample and the assay device. Do not reuse.
2) Re-draw sample and perform another assay with a new assay
device
NOTE: Make sure to wait for the sample tube prompt before
inserting the tube into the assay device.
This event may occur after a software upgrade or following changes
to the assay device.
1) Check the printing on the assay device pouch to ensure it is the
type of assay device desired. If not, obtain the correct assay device
type, and repeat the assay. If yes, perform an EQC test (see
Section 5.1). When running EQC, make sure to select the QC
prompt and not the assay prompt.
2) If EQC test is OK, attempt the assay again.
3) If the EQC is not OK or problem continues, call Customer
Support.
High light transmittance through the detection wells prevents the
instrument from measuring a change in optical signal.
In these cases, the event may be associated with the blood sample
and the following causes should be investigated:
•
The patient being tested has a hematocrit outside of the
applicable range. Refer to the package insert for information
on the range.
•
An improperly mixed sample was used to run the assay.
•
The sample was not run within the specified amount of time.
If none of the above can be determined to be the cause, run WQC
Level 2 (see Quality Controls Section 5.2.2) to confirm the integrity
of the assay device and the reagents. If the problem continues, call
Customer Support.
This event occurs when the EQC test detects the unfiltered light as
not within specifications.
Call Customer Support if the EQC device had been removed
completely at the end of the EQC and it fails.
