Early feasibility study with an implantable near-infrared spectroscopy sensor for glucose, ketones, lactate and ethanol

De Ridder F et al.

PloS one

Key finding

The implanted sensor measured glucose with a mean absolute relative difference of 7.4 percent, and its mean absolute differences were 0.12 mM for ketones, 0.16 mM for lactate and 0.18 mM for ethanol.

What the study did

This early feasibility study (GLOW) implanted a near-infrared spectroscopy sensor for 28 days in 7 participants, 4 with type 1 diabetes and 3 healthy volunteers. Metabolic challenges varied glucose and raised ketones (ketone drink, up to 3.5 mM), lactate (up to 13 mM) and ethanol, and sensor readings were compared with reference blood and breath measurements. The sensor was safe and well tolerated with no infectious or wound healing complications, and 6 of 7 sensors stayed fully operational for the whole period.

This study used [form], not goBHB. It is shown here as general ketone science. Only goBHB studies back goBHB product claims.
