Interstitial Fluid Biometrics

Meaning

Interstitial fluid biometrics are measurable physiological parameters, such as glucose, lactate, or certain hormone levels, that are quantified directly from the fluid surrounding the body’s cells, rather than from traditional blood sampling. This method, often facilitated by minimally invasive continuous monitoring devices, offers a high-frequency, dynamic view of metabolic and endocrine activity in the local tissue environment. These biometrics are increasingly valuable for assessing real-time physiological responses to diet, exercise, and pharmacological agents, bridging the gap between blood chemistry and cellular function.
