Software defect; Ortho Clinical Diagnostics received complaints of observed results from diluted samples that were reported as <2.39 mIU/mL (IU/L) instead of the correct No Result, which is accompanied by an Invalid Dilution (ID) code. The diluted results were inconsistent with results from the neat (undiluted) sample, which was within the measuring range of 2.39 - 15,000 mIU/mL. OCD's investigation determined it is possible to obtain negatively biased results if samples are diluted and tested on the VITROS ECi/ECiQ System using VITROS B-hCG II Reagent Packs, Lots 0484 and above.
