Manufacturer Narrative

This is our combined initial and final report on this incident.

Event Description

The customer reported a weak false positive reaction of biotestcell-a2 with the anti-a1 lectin reagent of a competitor.The customer provided the complaint product sample, but not the anti-a1 reagent used in this testing.At the time we received the complaint sample on our premises, the supposedly defective product was already expired.Within its shelf life our quality control laboratory tested their retention sample of the allegedly defective lot of biotestcell a2 with the anti-a1 lectin reagent and could confirm customer´s finding: the supposedly defective product yielded a weak false positive reaction.Additionally biotestcell-a2 was tested with seraclone anti-a1 and yielded a correctly negative reaction.The weak false positive reaction was only observed with the anti-a1 lectin reagent of a competitor.Based on this false positive reaction we initiated further actions.A review of the batch record documentation showed no irregularities which might have negative influences on the quality of the allegedly defective lot.
