Event Description

Siemens technical operations internal investigation has identified that discordant falsely low results were obtained on two investigational samples on an immulite/ immulite 1000 instrument when using the br-ma (ca15-3) assay.The two investigational samples were spiked with biotin at multiple concentrations and run for investigational purposes on an immulite/immulite 1000 instrument.The results of the two samples spiked with 500 ng/ml of biotin were falsely low with a bias of -71% and -51% respectively compared to results of the two samples without biotin.There were no patient samples impacted as this was for investigational purposes only.
