A Lab In Your Hand

Proxim has developed a next-generation handheld immunodiagnostic device. The system performs the most important laboratory tests near the patient using whole blood without any sacrifice in sensitivity and precision, bringing the most critical information to the doctors right when they need it. The instrument is battery operated, has touch-screen display interface, wireless, Ethernet, and USB connectivity.

Procalcitonin (PCT)

According to CDC, every year at least 1.7 millions American adults develop sepsis and early 270,000 dies. For each hour sepsis treatment is delayed, the patient's risk of death increases by 4 percent, making our point-of-care solution especially valuable. PCT allows differentiation of patients where sepsis is caused by bacterial infection.
