Errors 5006, 5007, 5008 and 5009 (Probe Check Control Failed) sometimes appear on the Cartridge-based Nucleic Acid Amplification Test (CBNAAT) machine in TB laboratories and need troubleshooting.
Problem:
Probe Check Control (PCC) failed, and the test was stopped before amplification.
Origins:
- Incorrect storage of cartridges (probe integrity issues detected)
- Dust on optical filters
- Sample too viscous
- Incorrect sample volume
- Improper fluid transfer (bubbles)
Solutions:
- Store the kits between 2 - 28°C.
- Use an optical brush to clean the optical filters (without a cleaning solution).
- Make sure the sample is totally liquified before transferring it to the cartridges.
- Add the correct volume of the specimen.
- Avoid making bubbles.
