Official wording
Reason: Quality control (QC) drift when certain lots of Performance Verifiers (PVs) are used with certain lots of cholinesterase enzyme (CHE) slides. This drift occurs when the PVs are used 2-7 days after reconstitution; however, the label stability claims for the PV fluids is 7 days following reconstitution. This may lead to inaccurate QC results. The use of the PVs when the QC results are outside of the customer s established ranges could result in delayed results for patients due to the need to repeat QC testing or reconstitute new PV fluids and repeat testing. It could also result in erroneous patient results (small positive bias).
