Siemens technical operations internal investigation has identified that discordant falsely low results were obtained on two investigational samples on an immulite 2000/ immulite 2000 xpi instrument when using the thyroglobulin assay. The two investigational samples were spiked with biotin at multiple concentrations and run for investigational purposes on an immulite 2000/immulite 2000 xpi instrument. The results of the two samples spiked with 19 ng/ml of biotin were falsely low with a bias of -35% and -33% respectively compared to results of the two samples without biotin. There were no patient samples impacted as this was for investigational purposes only.
