Recall Details

Company:
Siemens Healthcare Diagnostics, Inc.
Reason for Recall:
Siemens Healthineers has received customer complaints and confirmed imprecision for Quality Control (QC) and patient samples with Dimension Tacrolimus (TAC) lots GA2286, GA3047 and GA3171. The health consequences of erroneous patient results are major, since in a worst case scenario, a patient s tacrolimus dosing could be altered, resulting in potential organ failure and rejection (due to too low or no tacrolimus being administered) or toxicity (due to too much tacrolimus being administered). Siemens internal investigation of the Dimension TAC assay showed the worst case imprecision with patient samples at the low end of the Analytical Measurement Range (AMR). A patient sample at 2.0 ng/mL (2.6 nmol/L) recovered as 0.0 ng/mL (0.0 nmol/L) (100% negative bias), another patient sample at 2.1 ng/mL (2.7 nmol/L) recovered at 4.3 ng/mL (5.6 nmol/L) (103% positive bias).
Classification:
Class I - Dangerous

Dangerous or defective products that predictably could cause serious health problems or death.

Status:
ongoing

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

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.
