Siemens Healthcare Diagnostics Inc Recalls

April 2, 2026

epoc BGEM BUN Test Card (25 pk) for the epoc Blood Analysis System; Siemens Material Number (SMN): 10736515;

Use of the affected product can result in discrepant low pH and measured Total Carbon Dioxide (mTCO2) results and corresponding calculated values in arterial, venous, and capillary patient samples. An erroneously low pH or mTCO2 reading can lead to inappropriate treatment of nonexistent acidosis (respiratory of metabolic) or missed diagnosis of alkalosis (a true high pH: respiratory or metabolic alkalosis), potentially causing harm through unnecessary interventions with the former or failure to deliver appropriate treatment with the latter.

Dimension Creatinine Flex reagent cartridge. Material Number: 10872079.

Siemens Healthcare Diagnostics is recalling certain lots of Dimension Creatinine Flex reagent cartridge (Dimension CRE2) because a potential imprecision in the Dimension CRE2 quality control (QC) and patient sample results using lot numbers GA6307 and BA7005 on the Dimension System. This imprecision may lead to erroneously decreased or increased creatinine patient results

Atellica CH Enzymatic Hemoglobin A1c (A1c_E); Siemens Material Number (SMN): 11097536;

A potential for depressed results for Atellica CH A1c_E when processing Atellica CH RCRP on the same analyzer. Customers processing A1c_E and RCRP on separate analyzers are not impacted by the recall. The frequency and magnitude of the negative bias and imprecision increase over time and are not consistent with the assay Instructions For Use (IFU). When this issue is present, Quality Control (QC) results demonstrate a negative trend and increased imprecision. The clinical impact of a negative (A1c_E) bias may lead to a delay in diagnosis for diabetes or lead to less-than-optimal treatment for existing diabetes.

RAPIDPoint 500 Systems Wash/Waste Cartridge (4 Pack). Material Number: 10329097.

Siemens Healthcare Diagnostics is recalling the RAPIDPoint 500 Systems Wash/Waste Cartridge Lot WW/08925 due to a manufacturing error causing positive and negative bias in Ionized Calcium, Potassium, pH, Chloride, pCO2, Glucose and Lactate analytes and their derivatives. Four complaints were filed related to this event that led to Siemens Healthcare Diagnostics identifying an error in the manufacturing process and initiated corrective actions. Use of the affected device may result in errors during QC which could lead to a delay in patient treatment. If bias generated from this issue is not caught during QC erroneous results may cause temporary or medically reversible adverse health consequences to patients.

Software version 5.3 in: RAPIDPoint 500e Blood Gas System (USA) Siemens Material Number: 11416751 RAPIDPoint 500e Blood Gas System (China) 11416752; RAPIDPoint 500e Blood Gas System (Japan) 11

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.

DCA Systems HbA1c Reagent Kit

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%.
