Resolution
Typical causes of this event include a dirty port connection, use of
an incompatible sample tube, and not inserting the sample tube
firmly against needle hub.
1) Keep the assay device for troubleshooting, and verify the
detection wells filled with blood and the correct Greiner tube was
used. Refer to Section 6.2, Patient Sample Collection for more
information.
2) Use the cleaning device (see Section Error! Reference source
not found.).
3) Perform an EQC test (see Section 5.1)
4) If the EQC is OK, run a Wet QC Level 1 (see Section 5.2.1) and
verify the result falls within expected range.
5) If the EQC is not OK, call Customer Support and have the assay
device handy.
Either the sample tube/assay device was removed by the operator
before the test was completed OR a non-compatible tube was used.
1) Inspect the tube, and verify that the correct Greiner tube was
used. Refer to Section 6.2, Patient Sample Collection for more
information.
2) Discard the sample and the assay device. Do not reuse. Re-draw
a blood sample.
3) Wait for the prompt before removing the assay device during the
next assay (see Section 6.4).
NOTE: Once an assay has started, do not remove the assay
device or the sample tube until prompted, or until after aborting
the assay.
1) Power the instrument off. Wait 10 seconds, and then power it on.
2) Perform an EQC test (see Section 5.1)
3) If the EQC is OK, run a Wet QC Level 2 (see Section 5.2.2) and
verify the result falls within expected range. If so, proceed with the
assay.
4) If the EQC is not OK or the WQC produces an error, call
Customer Support.
Typically, this event occurs when a routine user has not been given
the authority to perform a diagnostic EQC test.
1) Have an operator with QC authority return to the Main Menu
screen and Login.
2) Perform an EQC test (see Section 5.1).
3) If the EQC is OK, verify the authority level of the original user (see
Section 8.6), and update, if necessary.
4) If the EQC is not OK or the problem continues, call Customer
Support.
