Calibration of CBNAAT

Calibration is an important step in restoring the optimal functionality of medical equipment. Periodic calibration of the Cartridge-based Nucleic Acid Amplification Test (CBNAAT) is required to retain the accuracy of the tests conducted by the CBNAAT machines.

Calibration of CBNAAT

Cepheid recommends that the instrument be recalibrated after one year of use, based on the initial installation date (or based on the previous calibration for subsequent years) or at 2,000 tests per instrument module, whichever comes first. The system monitors the number of tests since the last calibration.

Cepheid Technical Support can be contacted when a calibration reminder is displayed. The Assistance section can be seen in the Preface for the contact information.

Steps for Calibration

1. To check whether the instrument requires calibration, in the Maintenance window (Figure 1), look at the ICORE Starts Since Cal column. On the maintenance menu, click Module Reporters.

The Module Reporters window appears (Figure 2).
