The BioCheck Powder Screening Test Kit can be used by first responders as a first step to investigate suspicious powders for bioterrorism agents. 20/20 GeneSystems' kit works by quickly identifying the presence or absence of a biomolecule found in all living materials and many toxins. It therefore provides a rapid screen for the possible presence of multiple bioterrorism agents, such as anthrax and ricin toxin, while ruling out most of the ordinary substances that citizens have frequently feared to be possible weapons of mass destruction.
