The cause for the discordant vb12 results is unknown. The customer was running samples during the weekend (as not everyone is yet trained on the system). The customer was also not sure if the samples could be frozen. Therefore, one sample was placed in the freezer and the other sample in the refrigerator. Siemens healthcare diagnostics is investigating. The ifu states in the specimen collection and handling section: "do not use samples that have been stored at room temperature for longer than 8 hours; tightly cap and refrigerate specimens at 2-8? C if the assay is not completed within 8 hours; freeze samples at or below -20? C if the sample is not assayed within 48 hours; freeze samples only once and mix thoroughly after thawing. "
