Manufacturer Narrative

The observed discrepancy is most likely due to the sample being a weak positive for the flu a that is at/near the limit of detection (lod) of the assay.Low viral load specimens that are near the assay lod may not generate consistent results upon repeat testing according to expected statistical variances in detection.This is a sample-specific issue and the reagent is performing as intended.

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 united kingdom 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 the sars-cov-2 target and negative results for the influenza a and influenza b targets.The same sample was retested twice on the cobas liat analyzer and generated negative results for all targets.A recollected sample was tested on a competitor assay (genexpert) and generated a negative result for sars-cov-2.No harm was alleged.An investigation was conducted to evaluate the customer issue.Per fda¿s eua guidance, 1 mdr will be filed.
