Reason/Issue |
- Siemens has observed an increased frequency of Max Fit Deviation flags using the LSP calibrator kit lot 303574 (vial lots 122IT – 127IT) to calibrate the Alpha-1-Antitrypsin (AAT) assay. The Max Fit Deviation flag impacts the Level 2 calibrator (123IT) for the ADVIA Chemistry Systems Alpha-1-Antitrypsin (AAT) assay. While there is a potential for delay in alpha-1-antitrypsin results due to calibration failures, the risk to health as a result of this issue is negligible.
- The LSP calibrator IFU version that resided on the Siemens Document Library from December 10, 2013 until April 7, 2014contained preliminary calibrator values that differed slightly from the final calibrator values for the following ADVIA Chemistry Systems assays: AAG, AAT, ASO_2, C3, C4, FRT, HAPT, IGA_2, IGG_2, IGM_2, PREALB, RF and TRF. The differences between either the final or preliminary calibrator values would not affect the utility of these tests in clinical practice. |
