On August 9, 2019 the firm distributed Urgent Medical Device Recall Communication letters by via FedEx overnight courier and/ or ORTHO PLUS e-Communications and/ or US Postal Service Priority Mail (for PO Boxes only) summarizing the reason as Ortho Clinical Diagnostics determined that VITROS 7% BSA and VITROS Urine Electrolyte Diluent (UED) do not meet the current OAS time of d 7 days when stored on the VITROS 250/350 System in a 2mL cup only. Orthos internal testing compared results from samples diluted with diluent stored on the analyzer versus fresh diluent. When using 7% BSA or UED stored in a 2mL cup for 7 days, the differences in the results vs fresh diluent were >10% for some assays. It explained as a resolution: " The OAS of 7% BSA and UED in 2mL cups has been revised to d24 hours. " Current OAS time remains at d7 days for storage in 5mL and 10 mL bottles. " The Instructions for Use and appropriate User Documentation will be revised at a future date.
