Always run the verification one more time. If the failure repeats, contact customer service. There are different possible causes of verification failures. For example, "Noise Fail, Accuracy Pass" indicates that the MICT values and FIT values are accurate. Noise failure can be attributed to the following:
- Contamination on the cassette strip. Clean the strip gently with a Kim wipe.
- A noise source, such as an operating centrifuge, or operators moving things on the bench next to the instrument. Turn these instruments off or relocate the instrument.
- Contamination of the MICT sensor. Use a cleaning cassette before re-testing the verification cassette.
