On (b)(6) 2020, the customer reported non-reproducible erroneously elevated sars-cov-2 igg (access sars-cov-2 igg assay, part number c58961 and lot number 971196) patient results were generated on the customer's access 2 immunoassay analyzer (part number 81600n and serial number (b)(4)).The sars-cov-2 igg test was repeated with the same samples on a different access 2 immunoassay analyzer (part number 81600n and serial number (b)(4)) ,and lower results were obtained.The results from the instrument serial number (b)(4) were reported out of the laboratory.There was no report of change to patient treatment or management reported in association with this event.No hardware errors or other assays issues reported in conjunction with this event.Calibration performed on 13sep2020 passed.It was noted that the calibration showed "pex" flags indicating the open pack stability time had elapsed for the reagent pack.Other system performance indicators such as system check were not provided for review; customer was not running quality control samples and therefore no quality control results were provided for review.Sample collection and processing information such as sample type, volume collected, storage and handling conditions such as temperature and centrifugation time and speed, or other sample processing information was not provided.
