The Firefly Dx detection device from PositiveID Corp. has successfully tested 12 different assay types in prototype form, the company announced on Monday.

The Firefly Dx is a device that utilizes polymerase chain reactions (PCR) in order to detect the presence of a pathogen as well as potentially identify it. The testing assays were both specifically designed by the company and by third parties. In testing all pathogens were identified within approximately 20 minutes.

“We are very pleased with our progress with the testing and optimization of Firefly Dx and are confident that with continued development success, we will be able to deliver a real-time PCR system that can revolutionize point-of-need biological detection from an ease of use, time and cost perspective,” PositiveID Chairman and CEO William Caragol said.

The device was designed to be utilized by first responders and other emergency personnel in cases where traditional diagnostic methods based on laboratory equipment is unavailable. According to the company, these methods can take many hours or days to produce a result. The device aims to provide laboratory-quality results for pathogens and other contaminants.

The handheld device does not need any other external equipment, and all testing reagents are built into the device, allowing a quicker result.
