Reason for recall

The calibration for the affected batch of analyzers was incorrectly set during the manufacturing process which may lead to a failure when calibration is first performed. There may also be e remote possibility that incorrect qualitative test results for patient samples near the assay cutoff may be reported.

Potency and specification recalls happen when a batch tests outside its approved limits for strength, purity or dissolution, which can mean the dose delivered is higher or lower than labelled.
