Reason/Issue Internal investigation results by Roche Diagnostics confirmed that certain lots of Diluent Universal may have an influence on the CMV IgM results and may lead to low or false negative results with two lots of the Elecsys CMV IgM assay. Roche confirmed that a specific component used in the Diluent Universal caused the signal reduction of an internal control sample in the Elecsys CMV IgM assay. This internal control sample showed a high reactivity against one of the three specific antigens included in the CMV IgM assay. The signal reduction has only minor effects on the calibrators and controls (PreciControl CMV IgM) and therefore is likely to remain undetected, resulting in false non-reactive CMV IgM results and undetected acute CMV infections. In summary, there is a reasonable probability that the use of affected diluent lots may lead to delayed or incorrect diagnosis and/or treatment of acute CMV infection.
