A customer contacted beckman coulter inc. (bci) stating that the data generated during lot to lot correlations for the active inhibin a elisa methodology did not meet the laboratory's expectation criteria. The customer indicated that the lot is exhibiting a positive bias when compared to older lot samples recoveries. Customer indicated comparison data did not meet own comparison data expectation criteria with patient samples demonstrating an average increase of 16. 6% across all samples when using new reagent lot compared to an older lot. The customer also indicated that the comparison assay analysis was performed on multiple days and not a true side by side analysis. The customer sent nine (9) samples to an alternate methodology for comparison purposes. The comparative data shows sample recovery which is approximately 37% lower than the alternate methodology. The studies did not include any patient samples that were used for reporting. The customer did not report affect to the patient or user attributed or connected to this event.
