About
Proactive Dx develops Q-SENS, a waveguide-based, capillary-blood platform that brings central-lab immunoassays to the home. Their research spans rapid microfluidics, silicon waveguide optics, and AI analytics to quantify virtually any protein biomarker—up to 32 in parallel—including cytokines, cardiac & metabolic markers, infectious antigens, and aging signatures, in less than 10 minutes. They focus on longitudinal immune profiling and resilience scoring for preventative, precision healthcare. The company was formed with a new founding team to build on and advance the Q-SENS technology originally developed at Proactive Diagnostics, and acquired all assets and IP from Proactive Diagnostics.
