Point-of-care testing aims to bring diagnostics directly to the patient-provider interaction, utilizing user-friendly methods that provide rapid results. Portable testing frees the patient-provider schema from infrastructural constraints, elevating healthcare standards in remote and time-critical contexts. Electronic readout is highly desirable for these portable biosensing applications from the perspectives of cost, speed, and ease-of-use. We present a microfluidic device implementing a purely electronic assay to separate and enumerate activated and un-activated T-cells to rapidly detect a systemic infection response. We will discuss the system architecture and design considerations underlying the presented assay as well as the state of efforts to fully miniaturize the device.
