Siemens Healthcare Diagnostics, Inc. recalls Atellica CH Enzymatic Hemoglobin A1c (A1c_E); Siemens Material Number (SMN): 11097536;

Recalled April 8, 2026 · FDA recall Z-1657-2026 · Siemens Healthcare Diagnostics

Hazard
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. · FDA Class II
