Introduction to Bioimpedance Spectroscopy (BIS)
Modern diagnostics rely on advanced tools to assess tissue health. One such innovation is bioimpedance spectroscopy (BIS), a method that measures fluid levels in the body with remarkable precision. This technology is particularly useful for detecting early signs of fluid imbalance, which can be critical for effective treatment planning.
How BIS Works
BIS uses multi-frequency electrical currents, ranging from 5kHz to 1MHz, to evaluate fluid distribution. These currents pass through tissues, measuring resistance and reactance. This data helps differentiate between extracellular and intracellular fluid levels, providing a detailed picture of tissue health.
One of the key advancements in BIS is the elimination of gel electrodes. Next-generation devices, like the SOZO, offer a more convenient and hygienic solution. These devices have been validated as equivalent to traditional methods, such as the U400, under FDA 510k clearance.
The Science Behind BIS
Bioelectrical Impedance Spectroscopy Lymphedema Diagnosis Methods The core principle of BIS lies in its ability to measure fluid resistance. By analyzing how electrical currents interact with tissues, it calculates the L-Dex score, a metric that indicates fluid imbalance. This score is derived from a comparison of affected and unaffected limbs, offering a clear diagnostic marker.
Studies, such as those by Fu et al., have demonstrated the reliability of BIS with an intraclass correlation coefficient (ICC) of 0.99. This high level of consistency makes it a trusted tool in clinical settings, enabling early intervention and improved patient outcomes.
