Recall Z-2931-2018— CSL Behring GmbH

Class II · Terminated

Class II FDA medical device recall by CSL Behring GmbH, initiated 2018-05-31, terminated 2021-02-12. It names one FDA 510(k) clearance: K060677. Product: N Latex CDT Kit. Reason: Siemens Healthcare Diagnostics has observed a negative bias for the carbohydrate-deficient transferrin (CDT) measurement when using the affected N Latex CDT lots in comparison to the HPLC method. CDT results in absolute concentrations may be influenced by patients transferrin levels and, therefore, results are reported as ratio of CDT to total transferrin, called %CDT. As the transferrin determination with N Antiserum to Human Transferrin is not affected, the observed effect leads to calculated %CDT values that show a negative bias of approximately 15% compared to the HPLC method. This could result in a shift of weak positive patient samples into the reference range of 1.19  2.47 %CDT which was derived from a study population of healthy adults. There are no control or calibrator materials that would catch this bias..
