Probe Check Control [PCC] of GeneXpert Technology

Probe Check Control (PCC) of Cartridge Based Nucleic Acid Amplification Test (CBNAAT) Technology tests the fluorescence readings of probes at different temperatures, before the start of thermal cycling.

PCC verifies:

• Re-hydration of beads
• Filling of the Polymerase Chain Reaction (PCR) tube
• Integrity of probes
• Stability of a dye or the reagents/ quencher.

The results are automatically compared to the pre-established factory settings in the software.

If the probe check fails, the test will abort. You can check the error message to review the cause of the probe check failure. If the probe check passes, the test continues (Figure).​
