Diagnosis of militarily relevant diseases using oral fluid and saliva antibodies: fluorescence polarization immunoassay.

This laboratory is developing fluorescence polarization (FP) methods as diagnostic tools to assay antibodies in saliva and other oral fluids. FP provides quantitation of molecular interaction, such as antigen-antibody binding, of a single, small-volume sample in real time and without prior separation of components such as blood cells. There is potential for wide-spread use of these homogeneous assays as noninvasive tests, especially as more compact, simplified fluorescence polarimeters become available.
