Positive bias for some samples around the CA 19-9 upper limit of normal of 35 U/m as compared to the previous lot. The sample bias observed was greatest in the Asia Pacific sample population. The observed bias is not proportional across the assay measuring interval and is less pronounced for sample results above a concentration of 110 U/mL.

During manufacturing, the last three tests from the 160 test flex of lot 23206BA (wells 8 or 10) were processed on the Dimension Vista platform. There was an issue with the filling line which led to some wells to underfill in lot 23206BA. Calibrator, quality control (QC) and patient results could have been impacted.

Siemens Healthineers has identified an issue with the RAPIDPoint500e system software version 5.3. This issue affects how the sample source is identified at the LIS when using the capillary mode. With this software version, samples run in the capillary mode are incorrectly labeled as arterial when displayed on the LIS, leading to the potential for results to be flagged according to an established arterial range. Capillary sample results are correctly identified as capillary on both the RAPIDPoint 500e system display and the instrument printouts. The issue only affects the new software version 5.3 and only capillary sample mode is impacted. The inability to distinguish specimen sources for blood gas may lead to incorrect diagnoses and management decisions.

The potential for falsely elevated patient sample results when using impacted lots (785, 790, 791, and 793) of IMMULITE 2000 Anti-TG Ab.

Potential for falsely elevated Chol_2, LDLC, and Trig_2 results on the Atellica CH and Atellica CI analyzers when the previous result in the cuvette was Iron3. Results in a positive bias ranging from 2-16% -impacts calibrator, quality control (QC), and patient results.

The reason for the recall is that the Siemens DCA HbA1c Reagent Kit was confirmed to display a positive bias without alerting the user. The potential impact of the defect is that erroneous test results could be reported and potentially lead to incorrect patient management of glucose control. A positive bias may be observed with eleven HbA1c affected lots. Positive bias was observed when the performance of these five HbA1c lots was compared to NGSP pooled patient target-value assigned samples and the maximum bias observed was 19%.

Siemens Healthcare Diagnostics has confirmed an average negative bias of -35% compared to the 3rd World Health Organization (WHO) International Standard (NIBSC code: 11/170) that is proportional across the assay measuring interval. The reference interval as claimed in the Instructions for Use (IFU) is not achieved with affected lots.

Potential for a negative bias with quality control (QC) and patient sample results when using the Atellica CH Immunoglobulin M_2 (IgM_2) reagent.

RAPIDPoint 500 Systems Measurement Cartridges (with lactate) has the potential to affect the Sodium (Na+) sensor to produce a negative bias that could result in serious injury due to a delayed diagnosis of hypernatremia or unnecessary intervention for hyponatremia and result in iatrogenic hypernatremia especially if the true sodium result is near the thresholds of severe alterations, as well as cause a Question Result -----? error flag for multiple electrolytes on patient samples and quality control that may cause a delay of diagnosis or treatment.

Siemens Healthcare Diagnostics Inc. has confirmed a potential issue that could occur under certain conditions, a software problem is causing erroneous results to be printed. When the results are run on the epoc NXS Host and Delete Blood Tests feature is enabled, the results that are generated at the time of testing are correct; however, when this issue occurs, results that are printed, saved and/or transferred to a data manager, may include unselected analytes that are from a previous patient or QC test. The worst possible outcome may result in a failure to diagnose hyperkalemia, due to an erroneous depressed potassium level or inappropriate treatment to hyperglycemia due to erroneous glucose reading.

There are potential drug interferences from Perhexiline Maleate or Atomoxetine Hydrochloride that may cause falsely elevated sodium results reported on the RAPIDPoint 500 and RAPIDPoint 500e Blood Gas Systems. The erroneous sodium levels with positive bias may lead to unrecognized hyponatremia and/or the inappropriate treatment of hypernatremia may lead to iatrogenic hyponatremia, resulted in a delay in patient diagnosis and optimal patient management.
