Abbott Assay—Basic Assay Troubleshooting, Continued
Assay Characteristics
If multiple assays are affected, look for similar characteristics
such as:
• Same line
• Assays using R1 only vs. assays using R1 and R2
• Similar wavelengths
• Same calibrators
• Same sample and reagent volumes
• Rate vs. end-point reaction
If the issue affects one assay:
• Verify assay parameters with the assay-specific package
insert
• Was a different bottle of reagent, calibrator, or control
used, and was it handled correctly?
• Was a different lot of calibrator or reagent used?
• Are there any non-Abbott assays on the original line? If so,
were carryover studies performed between those assays
and the affected assay?
• Move the assay to an alternate line. If the issue is not
resolved, proceed to step 2 of Instrument
Troubleshooting.
Instrument Troubleshooting
1. Is the issue on both lines? If yes, troubleshoot common
items, including:
•Lamp
• Cuvette washer
•Water
• Bulk solution use
•Maintenance
•Probe/mixer wash flow
