Which criterion indicates calibration drift on automated analyzers, and what actions are typically triggered by this drift?

Calibration drift is indicated when calibration checks fall outside the predefined acceptance limits, showing that the instrument’s response to known standards has shifted and measurements may no longer be accurate. When this happens, the typical actions are to restore accuracy by re-calibrating the instrument or replacing/updating the calibration curve as per policy. This specific trigger isn’t about maintenance timing, error codes, or just any QC failure: it’s about the calibration checks themselves deviating from acceptance, which signals that the calibration model no longer properly aligns the signal with true concentrations.
