No. Issue Description Resolution
1
Attention - Bubbles in
sample
One or more of the test
detectors received too
high a light signal.
This event can be caused by an air bubble in the sample, a very low hematocrit sample, or
incomplete reconstitution of the reagent.
1) Keep the test device for troubleshooting, and verify there were no bubbles in the
detection wells. Also verify that the correct sample tube has been used. If there are
bubbles present, use a cleaning device (See Section 1.1). If there are no bubbles present,
the blood sample may have a low hematocrit. See test package insert for details.
2) Perform an EQC test (see Section 5.1). If the EQC is OK, run WQC Level 1 (see Section
5.2.1).
3) If the EQC is not OK or the problem persists, call Technical Support and have the test
device handy.

Attention - Test device
lot expired
An expired test device
has been inserted into the
instrument.
1) Check the expiration date on the packaging of the test device as well as the current date
and time on the instrument.
2) If the test device has expired, remove it and discard.
3) If the instrument’s date and time is incorrect, change the setting (see
Section 8.3).
