Manufacturer Narrative

The complaint investigation for false nonreactive architect core results included a review of data and information provided by the customer, search for similar complaints, ticket trending review, labeling review, device history record review, and in house testing.Additionally return sample testing was conducted.Data and information provided by the customer were reviewed and support the complaint issue without indication for any additional issue.A search for similar complaints did not identify an increase in complaint activity.A review of tracking and trending did not identify any trends for the product for the issue.Device history record review did not identify any non-conformances or deviations associated with lot number 50607be00 and the complaint issue.In-house sensitivity testing was completed using an in-house retained kit with complaint lot number 50607be00.All controls met specifications and no false non-reactive results were obtained.The complaint lot detected the same bleeds of the seroconversion panels as reactive, as per the manufacturer data.Labeling was reviewed and found to adequately address the issue under review.The volume of the return sample was not sufficient to execute the complete test protocol as only 80 l were available for testing.Therefore, only the first test of the schedule (alinity s anti-hbc) was performed.Result for sample (b)(6) with alinity s anti-hbc generated a nonreactive result (0.13 s/co), and thus interpretation was in alignment with the customer result.A final disposition for the return sample was not possible due to the test algorithm not being completed.Based on the investigation, no systemic issue or deficiency of the architect core for lot number 50607be00 was identified.
