China NMPA Product Recall - ẞ2-Microglobulin Assay Kit (Latex Immunoturbidimetric Assay)

On December 3, 2021, the National Medical Products Administration (NMPA) announced a voluntary Class III recall initiated by Siemens Healthcare Diagnostics Inc., reported by Siemens Medical Diagnostics Products (Shanghai) Co., Ltd. The recall pertains to a specific medical diagnostic product, the B2-Microglobulin Assay Kit (Latex Immunoturbidimetric Assay), specifically batch number 211446. The primary issue identified is the potential for significant deviations in both quality control results and patient sample outcomes when using this particular batch of the B2-Microglobulin Assay Kit. Such deviations could impact the accuracy and reliability of diagnostic testing, potentially leading to incorrect patient assessments or treatment decisions. Under the NMPA's regulatory framework, the company has taken the required action of initiating a voluntary recall to address this quality concern. A Class III recall indicates that the product issue is unlikely to cause adverse health consequences, but corrective action is still necessary to prevent potential misdiagnoses or inappropriate medical interventions. Detailed information regarding affected product models, specifications, and batches is available in the accompanying Medical Device Recall Event Report Form.
