Customers were instructed to immediately implement Alternative 1 or 2 until the signal data PCB is replaced. Alterative I: Stop the use of all affected analyzers until corrective actions can be performed on these analyzers. Alternative 2: Verify proper function of the affected analyzers immediately following every patient sample measurement by measuring a manual QC sample.
