Oral administration of pyridostigmine bromide and huperzine A protects human whole blood cholinesterases from ex vivo exposure to soman

Due to the documented use of OPs by terrorists and in warfare around the globe, Federal, State, and local authorities need a reliable, fast, inexpensive, and standard method for confirming such an assault in order to initiate appropriate containment, decontamination, and treatment measures. This assay is ideal for prescreening military personnel for atypical ChE activities that would preclude their deployment to areas of potential CWA exposure. The WRAIR WB ChE assay will fulfill the requirement for rapid and reliable monitoring of such exposure in military and civilian populations.
