  • Reason
    It was identified, after receiving customer complaint, colored eluents for extractions of whole blood when using the nuclisens batch lysis buffer: 16092902. due to this fact an investigation was opened in the laboratory of research and development related to this product (pr 1082674). open investigation (pr1082674) has confirmed that the eluent becomes colored due to the presence of hemoglobin in the blood samples, including dry blood spot. in the case of dry blood spot, the investigation highlighted some cases of inhibition even though the eluents remain slightly colored. the root cause of the staining is linked with a non-compliance in terms of ph value of the lysis solution. it has been found that the ph of the solution in this batch is 6.9 when the ph specification for this solution is 7.1 +/- 0.1. research has confirmed that the presence of hemoglobin may cause inhibition of downstream applications (pcr / rtpcr / nasba etc ....), resulting in uninterpretable results in most cases. because the internal controls would also be inhibited, we would invalidate the test. in this case the risk is related to the delay in the emission of the diagnostic results. however, considering that the nuclisens lysis buffer is used in various protocols and downstream applications; and assuming a conservative positioning, we can say that the worst case scenario would be: internal control is not inhibited or not used, although this is part of the good laboratory practice procedures, the color eluent tests could have a potential result false negative investigations have confirmed that we have no other batch of the nuclisens lysis buffer on the market today presenting the same problem of non-compliance with ph.
