Siemens Healthcare Diagnostics, Inc. Atellica CH Enzymatic Hemoglobin A1c recall: A potential for depressed results for Atellica CH A1c_E when processing

Recall published 7 months ago

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.

The hazard: Device safety concern

This is a device enforcement record. Check whether the remedy is a correction, a software update or a removal before changing anything.
