Event Description

It was reported that while using the cd5 pe-cy7 ce that there were erroneous reults.The following information was provided by the initial reporter: 2) could you please inform us if samples are available? (customer mentioned: "in stock we have 2 more packs of cd5pecy7 from the same batch").As we said, we have 2 new packs of the same batch.3) was it obvious that the results were erroneous/could not be trusted? yes, because usually we don¿t need to make any change in the compensation matrix.4) is a confirmatory test always performed? we tested another new pack of the same batch that work properly for two weeks then even this one gave some problems in the compensation.It looks like the spillover of the pe-cy7 in the pe channel gradually increases.5) were patient samples involved? we work on primary samples from whole blood of cll patients.We perform an immunophenotype to characterize the cll for both diagnostic and research purposes.6) were erroneous results reported to the clinician? no, clinical markers could be evaluated through compensation.However it was difficult to evaluate the signal in the pe channel, in particular for some markers expressed at low intensity (for research purposes).7) were patients treated based on erroneous results? no.This is to inform you that we have encountered problems in detecting the fluorescence signal in 2 packs of cd5pecy7 cod 348810 lot: 2214258.With the first package, the problem occurred on first use.The second package, in use since 10.01.2023, gave no problems until yesterday but today it was necessary to change the compensation values during the analysis.In stock we have 2 more packs of cd5pecy7 from the same batch.
