Enabling Rapid Point-of-Care and At-Home Diagnostics

Our Technology

Proactive Diagnostics' novel Q-SENS platform uses waveguide-technology to allow highly sensitive and specific detection of various biomarkers (protein and nucleic acids), in a variety of bodily fluids – foremost, whole blood, easily drawn by a finger prick.

Our competitive edge lies in the combination of our ability to simultaneously test for a variety of markers in 32 sensing-wells (multiplexing), coupled with the test's simplicity and quick results (under 15 minutes), with kinetic detection that allows for monitoring the gradual rise in the target's presence binding and quantification of its concentration. All this makes our Q-SENS platform an extremely attractive point-of-care solution, which can be employed in transportation terminals, local pharmacies, GP clinics, schools and workplaces, or even ones' home. 

Point-of-Care Diagnostics

Point-of-Care (POC) testing has been the ‘Holy Grail’ of medical diagnostics for the past decades. Despite the pressing need and vast resources devoted to the field, the POC testing goal was never realized and at times seemed unattainable.  There are several ‘must-have’ requirements for a successful POC testing platform, including:

•  Performance (sensitivity and specificity) comparable to that of a central lab.

•  Quick results

•  Multiplexing capability - running several tests simultaneously.

•  Small sample volume (ideally, from a finger-prick) or other bodily fluids.

•  Simple to operate - minimal training required.

•  Low-cost consumable and instrument.

Proactive Diagnostics' Q-SENS platform meets all these requirements and more. Learn more about our unique solution here.

Use Cases
Proactive Diagnostics' Q-SENS platform has demonstrated exceptional performance on ~50 different assays (immunoassays and molecular), spanning a range of applications in fields of medical diagnostics, immunology, veterinary, food safety, dietary, and more.

We are currently focused on several solutions pertaining to the COVID-19 pandemic, including viral detection, antibody screening, and disease risk stratification. We also deal with immune system monitoring to detect inflammation which can prove highly effective in the early detection of a range of medical conditions, such as cancer, cardiovascular disease, diabetes mellitus, neurodegenerative disorders, and many more. Collectively, these mount to the leading causes of disability and mortality worldwide, and are associated with a prolonged state of chronic inflammation, that, if detected early, can be acted upon through a range of interventions in a due and timely manner.


We are happy to discuss new use cases for our technology on the basis of newly generated knowledge and lab-developed tests (LDTs), and widen the scope of our technology's applications. Contact us to explore collaboration!
