Measuring insulin at
picomolar sensitivity
Insulin circulates at 25–600 pM — one million times more dilute than glucose. That is why insulin measurement has never left the laboratory. Until now.
Why insulin is hard to measure
It's a protein, not a small molecule. It can't be sensed continuously. No wearable sensor exists, and none is in the FDA pipeline. Specialty immunoassay labs are slow, expensive, and disconnected from primary care workflows.
The science works.
Insulin circulates at 25–600 pM. We detect far below that range.
Accuracy across low, medium, and high concentrations.
Correlated against the gold-standard immunoassay.
Bench-validated shelf-life performance.
Bench-validated on plasma. Next milestone: whole-blood lateral-flow integration.
How the sensor works
Whole Blood Sample
~20 µL from a fingerstick. Passive capillary transport into the lateral-flow strip.
Multiplexed Electrochemistry
NiOx electrocatalytic insulin detection on a closed bipolar electrode architecture, co-located with glucose sensing.
CDSS Output
Insulin Sensitivity Score + Pancreatic Function Score fed into the 5-phenotype classification engine.
Five metabolic phenotypes. One test.
The same fasting glucose can reflect five different disease mechanisms. The CDSS classifies each patient and surfaces the appropriate clinical action.
