Supportive Data
IgG:
To evaluate the accuracy of the BioPlex Mumps IgG multiplex flow immunoassay (MFI), 500 prospective serum samples were analyzed in a blinded fashion by the SeraQuest Mumps IgG enzyme immunoassay (EIA) and the BioPlex Mumps IgG assay. Specimens with discordant results after initial testing were repeated using both assays during the same freeze/thaw cycle. Further discrepancies were evaluated by the Mumps IgG VIDAS enzyme-linked fluorescent immunoassay (ELFA; bioMerieux, Inc). The results are summarized below:
