The investigation determined the likely cause of the (b)(4) (alu is too small) condition codes is an issue associated with the vitros cov2 total reagent pack.It was determined, via econnectivity, that the two bottles which make up vitros cov2 total (pack id (b)(4)) were interchanged (swapped) during the manufacture process.Therefore, the correct reagents were not added in the correct quantities at the correct time during the processing of the assay.There was a total of 37 patient results obtained from vitros cov2 total pack id (b)(4).Of the 37 samples, 5 were associated with (b)(4) and the results for those 5 samples were suppressed.It is unknown if the any patient result(s) were affected or reported to a clinician.Since the customer did not report the result directly to ortho clinical diagnostics, it is assumed there were no allegations of patient harm.However, it cannot be concluded that patient sample results would not be affected if the event were to recur undetected.This issue is associated with investigation (b)(4) (anti sars cov 2 total and anti sars cov 2 igg reagent pack bottles switched).Ortho is in the process of issuing a customer letter to those who were shipped vitros cov2 total reagent lots which were manufactured using a manual process to insert the bottles onto the frame of the reagent pack.

This supplemental emdr 472708 is being created to update the initial emdr 472468 to include information associated with a recall issued on 17 july 2020 and customer communication (cl2020-191) sent 17 july 2020.The fda was notified of this issue on wednesday 15 july 2020.Refer to report number 1319681-07/15/2020-001-c.A customer communication (cl2020-191) was sent 17 july 2020 to all customers who were shipped affected lots of vitros anti-sars-cov-2 total and vitros anti-sars-cov-2 igg reagent.The letter indicates if the two reagent bottles are interchanged (swapped), the correct reaction scheme does not occur.This can result in false negative results for a sample that is reactive, calibration failures and quality control failures for the reactive control.The letter instructs customers to visually inspect the reagent pack prior to loading to ensure correct reagent bottle configuration.
