Recalls for Radioimmunoassay, Cortisol

Beckman Coulter has confirmed a software anomaly on DxI 9000 Access Immunoassay Analyzer and the DxC 500i Clinical Analyzer that may prevent correct application of user-specified manual dilution factors when ordering additional tests for samples already "In Progress" using the same "Sample ID number". This can lead to false low or high patient results and potential delays in reporting, risking erroneous diagnoses if undetected.

On a clinical analyzer, when ordering a Clinical Chemistry (CC) combination test simultaneously with an Immunoassay (IA) test, if the IA test is processed between the CC tests, CC sample status will remain In Progress with no errors, may cause processing delays.

The Access Cortisol assay protocol file (APF) applies an incorrect calibration curve acceptance parameter at the S1 calibrator level that can lead to a high rate of calibration failures which can vary by reagent lot number. Calibration failure would lead to delay of measurement results reporting and potential injuries.

Customer complaints were received for positive bias reported on the controls used on the IMMULITE /IMMULITE 1000 on the Cortisol Assay reagent lots IMMULITE /IMMULITE 1000 (LKCO1) Lots 381,382 and 383 . Subsequently, the firm confirmed a positive bias on the IMMULITE/IMMULITE 1000 (LKCO1) Lots 381, 382 and 383.

The recall was initiated because Beckman Coulter has confirmed that the listed lot numbers of Active Control ELISA reagent will result in falsely high values for patient samples due to a shift in the calibration of the assigned standard values. Beckman Coulter recommends that patient results, generated with the affected lots, be evaluated in the context of other diagnostic tests and the clinica

The recall was initiated by Beckman Coulter after the firm confirmed customer reports that the affected lot of Access Cortisol reagent (REF 33600) identified above may produce suppressed patient results. Beckman Coulter also confirmed customer reports that the two lots of Access Progesterone reagent (REF 33550) identified above may produce suppressed patient results and an increased incidence of I

Cross contamination may have occurred between wells for the reagent pack. As a result of this defect, patient results may be negatively impacted (falsely decreased) by up to 16%).
