PositiveID Corporation Meets Major Development Milestone: New Firefly Dx Prototype With Real-Time Optics for Pathogen Detection

Real-Time Optics Enable the Firefly Dx System to Quantify the Amount of Pathogen Present in a Sample and Qualify the Test Result, Which are Critical Measurements in Field Applications and Advantages of Real-Time PCR Testing

DELRAY BEACH, Fla., Oct. 12, 2015 (GLOBE NEWSWIRE) -- PositiveID Corporation (“PositiveID” or “Company”) (OTCQB:PSID), a developer of biological detection and diagnostics solutions, announced today that it has produced a new and upgraded version of the Firefly Dx polymerase chain reaction (“PCR”) breadboard prototype pathogen detection system (“prototype system”), which now incorporates real-time optics for pathogen detection in less than 20 minutes.

The inclusion of real-time optics on the Firefly Dx prototype system enables the measurement of fluorescence with every cycle of the PCR process, which is used to understand the amount of pathogen present, and produces an “S-shaped” curve that can be identified. The S-shaped curve helps first responders and healthcare professionals understand the quality of the test being performed and to quantify the amount of pathogen present in the sample, both of which are important in determining next steps (such as quarantine measures) following a positive result.

This latest development advancement also enables the Company to run its own and third-party assays directly on the Firefly Dx prototype system, without the need to use a commercial instrument for confirmation of results.

“This new prototype system is a big step forward in the development of a commercially available Firefly Dx unit as we move to capture a portion of the multi-billion dollar real-time PCR market,” said William J. Caragol, Chairman and CEO of PositiveID. “By incorporating real-time optics into our system, we can begin to measure the presence of a pathogen in real-time, which is an integral component of the Firefly Dx value proposition.”

PositiveID's Firefly Dx is designed to provide real-time, accurate diagnostic results in less than 20 minutes from a handheld device, thereby leading to treatment scenarios at the point of need that are not possible with existing systems, which require lab-based equipment, highly trained personnel, and can take hours or even days to provide results. Firefly's applications include point-of-need, lab-quality, detection of pathogenic organisms; agricultural and food screening in both domestic sectors and developing countries; and detection of biological agents associated with weapons of mass destruction.

The Company previously announced production of the Company's first article, molded PCR chips for the Firefly Dx cartridge, which enables it to produce large quantities of PCR chips at a lower cost, thereby enabling higher throughput of testing data and cost-effective field applications. PositiveID is now able to incorporate and optimize additional assays on its Firefly Dx cartridge with a disposable PCR chip.

Firefly Dx is targeting the global PCR market, which is projected to reach approximately $27.4 billion this year, according to a Research and Markets' report Polymerase Chain Reaction (PCR) - Products/Tools - A Global Market Watch, 2009-2015.
