PositiveID Corporation ("PositiveID" or "Company") (OTCQB:PSID), a developer of biological detection and diagnostics solutions, today announced that it has published a report on the current market opportunities for its homeland security and medical diagnostics technologies.

"The bio-detection market has seen a surge in funding over the past decade," stated William J. Caragol, Chairman and CEO of PositiveID. "This increase can be directly attributed to events that have occurred since the beginning of the 21st century such as the Anthrax scare in 2001, the SARS outbreak in 2003, the ricin letters in 2004, the H1N1 health crisis in 2009, and most recently the concern over Syrian and North Korean biological and chemical weapons programs."

Mr. Caragol continued, "The urgent requirement for public healthcare and homeland security agencies to institute an early detection system for bio-terrorist attacks and infectious disease outbreaks is at hand. PositiveID's technologies reduce the time to both detect the presence of a threat and diagnose affected persons, enabling the deployment of countermeasures and vaccines in a time frame where casualties and fatalities can be drastically reduced. Our products are capable of revolutionizing not only our nation's response to bioterrorism but also improving medical testing at the point of need."
