Light measures glucose. Enzymes don't.
GluTronics reads blood glucose via near-infrared optical spectroscopy — directly, in real time, with no interstitial fluid intermediary and no consumable sensor to replace.


Spectroscopy, not biochemical inference
The sensor emits calibrated near-infrared wavelengths through tissue. Glucose concentration is derived from the absorption signature of whole blood — no enzymatic reaction, no electrochemical oxidation step.
Because measurement occurs in the capillary bed, not the interstitial fluid compartment, the 5–15 minute physiological delay endemic to enzymatic CGM systems is structurally absent from this architecture.


The 15-minute problem, removed by design
Enzymatic sensors read interstitial fluid — a compartment that lags whole-blood glucose by 5 to 15 minutes. Every clinical decision built on that data inherits that error.
Optical spectroscopy captures the blood signal directly. Zero ISF compartment. Zero diffusion delay. Readings reflect physiological state as it exists, not as it existed.


Accuracy validated across all six skin tones
Legacy optical systems degrade in accuracy at higher melanin concentrations. GluTronics' multi-wavelength calibration algorithm was developed and validated across the full Fitzpatrick I–VI range under IRB-approved protocols.
Skin-tone agnostic performance is not a secondary specification — it is a clinical accuracy requirement built into the optical stack from the ground up.
