App-derived interpretation

Unknown reason.no_named_rule · v1.0.0
VITROS TSH reagent lots have been found to generate higher than expected Calibrator level 2 signals on some customer systems. These Calibrator Level 2 responses cause a higher than expected frequency of customer generated calibration curves to fall outside of the calibration quality parameter measuring the gradient of the Customer Calibration Curve between Calibrator Level 2 and Calibrator Level 3.

These labels are deterministic app interpretations, not FDA categories.
