If customers have an alternate lot of the ADVIA Centaur or ADVIA Centaur CP Folate assay, they are instructed that this lot should be used for future testing. However if no alternative lot is available, quality control (QC) results should be obtained for each individual ReadyPack as a QC or calibration is an indication of an affected pack. An affected pack must be replaced with a different Folate ReadyPack where a valid calibration and acceptable QC values are obtained.
