Manufacturer Narrative

Event Description

The customer reported a false positive reaction of cell no.8 (donor no.103493) of ih-panel 11 with anti-n.According to the antigen table cell no.8 was n antigen negative, but mmss.The customer stated that they received a positive reaction with cell no.8 of ih-panel 11 and seraclone anti-n.The customer intends to return a product sample for investigational tesing but hasn't done so yet.Therefore, our quality control laboratory tested their retention sample of the supposedly defective lot.Cell no.8 of ih-panel 11 was tested with seraclone anti-m and seraclone anti-n according to the instruction for use (tube test, incubation for 30 minutes at room temperature, reading of the results; no centrifugation).Cell no.8 of ih-panel 11 showed a correctly negative result with seraclone anti-n, while the reaction with seraclone anti-m was correctly positive.The positive and negative controls also showed a correct result.We did not observe any false positive reaction.Based on the current tests of our quality control laboratory, a mistyping of cell no.8 of ih-panell 11 (donor no.103493) can be excluded.The donor 103493 has already been in use for the paned reagent red blood cells for four years.A review of the batch record documentation showed no irregularities which might have negatively affected the quality of the allegedly defective lot.
