ZMYND10 and influenza: The major advantages of the mPlex-Flu assay are the ability to precisely quantitate multiple influenza antibody reactivities simultaneously in a large number of samples utilizing a very small sample volume, its continuous readout, a high specificity with low intra- and inter-assay variability, and an ability to detect very low levels of anti-HA Ig within a broad 4 Log10 range of detection.
