Resolution
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 assay 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 Error! Reference source not found.). If there
are no bubbles present, the blood sample may have a low
hematocrit. See assay 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 Customer
Support and have the assay device handy.
NOTE: Make sure to gently invert the sample as specified in
Section 6.4 to avoid bubbles.
1) Check the expiration date on the packaging of the assay device
as well as the current date and time on the instrument.
2) If the assay device has expired, remove it and discard.
3) If the instrument's date and time is incorrect, change the setting
(see Section 8.3).
This error may occur if the instrument is located under bright light or
if the spot code on the assay device does not match the bar code
scanned from the assay device pouch (lot information).
Place the instrument away from direct sunlight, bright light, or
other radiant heat sources (refer to installation guidelines).
1) If the error occurs when running an assay, check to see if the spot
code label is marred or crooked. If so, use another assay device.
2) If this error occurs while attempting to run an EQC, turn the
instrument on and off. Next, perform another EQC (see Section 5.1).
3) Scan the bar code from another pouch from the same lot (do not
open the pouch).
4) If the problem continues, call Customer Support.
1) Press the Back key, and scan a bar code from another
pouch from the same lot (do not open the pouch).
2) If this does not work, perform an EQC test to ensure the
instrument is working properly (see Section 5.1). If EQC is OK, try
the assay again.
3) If the EQC is not OK or the problem continues, call Customer
Support.
