Manufacturer Narrative

An investigation was conducted to evaluate the customer issue.Note, while the customer indicated the alleged sample was tested on (b)(6) 2022, the provided data indicated the sample was tested on (b)(6) 2022.Throughout the data analysis, a systematic issue was not observed and a product problem was not found.Overall, the most likely cause for the discrepant results may be due to a reagent or sample handling issue or cross-contamination.In addition, the lod and the type of influenza viral strains detected differ significantly between the cobas® sars-cov-2 & influenza a/b assay on the cobas® liat system and the cepheid genexpert assays.As such, results with one assay may not be reproducible with a different assay.(b)(4).
