A siemens healthcare diagnostics inc. (siemens) customer service engineer (cse) and a technical application specialist (tas) were dispatched to the customer's site to determine the cause of the potential false negative d-dimer results on the bcs xp system. During the investigation, the cse observed that the calibration curve, used to run patient samples, on the bcs xp system was unacceptable. The cse changed the reagent lot, calibrated the system, replaced the sample probes, and flushed the bcs xp system of the barbicide disinfectant cleaner. The precision test, validation and lamp were within specifications. The internal qc recovered within expected ranges. Upon further investigation, siemens determined that the customer is using recycled cuvette rotors. Based on the bcs? Xp system's instruction manual, cuvettes are only intended for single use. If used more than once, this could result in inaccurate measurement results. The use of recycled cuvette rotors is a user error and potentially contributed to the discordant result. Siemens has instructed the customer to discontinue the use of recycled cuvette rotors. The system is performing according to specifications. No further evaluation of this system is required. Mdr 9610806-2017-00098, mdr 9610806-2017-00099, mdr 9610806-2017-00100, and mdr 9610806-2017-00102 were filed for the same event.
