Manufacturer Narrative

Throughout the data analysis, a systematic issue was not observed and a product problem was not found.The sars-cov-2 result generated for the initial run, shows a delayed amplification curve and is a true amplification.The observed curve is aligned with a low titer sample at the limit of detection (lod) where results can waiver on repeat testing.The influenza a result on first run shows a strong positive result with the curve showing a sigmoidal growth that is aligned with a true positive result.The second run also generated a strong influenza a result that was a true positive result.There is no discrepancy on this target.Both sars-cov-2 and influenza a target results are true positives.The most likely cause for the discrepancy observed is due to the sample having a low viral load, either from a patient with a low titer or from lab cross-contamination, where results are known to waver upon repeat testing.(b)(4).

Event Description

In light of the covid-19 pandemic and the subsequent emergency use authorizations (euas) for sars-cov-2 diagnostic tests, the agency has requested heightened reporting beyond the reasonably suggests requirements of 803 to include allegations of false positive or false negative results independent of harm or malfunction or off-label use.Pursuant to the agency¿s instruction, we hereby submit this mdr.A customer from the us alleged a discrepant result for a single patient while using the cobas® sars-cov-2 & influenza a/b nucleic acid test on the cobas® liat® system.The alleged sample initially generated a positive result for sars-cov-2 and influenza a and a negative result for influenza b.The same sample was retested on a different cobas® liat® system and a different platform (genexpert) and both time the samples yielded a positive result for influenza a and a negative result for sars-cov-2 and influenza b.The initial positive result was released.No harm was reported.An investigation was conducted to evaluate the customer issue.Per fda¿s eua guidance, 1 mdr will be filed.
