The BIA device measures body water percentage and estimates the body composition based on the assumption of normally hydrated lean mass of 73%. These are optimal conditions which are not commonly reproducible. BIA determines Total Body Water (TBW), Extracellular Water (ECW) and Intracellular Water (ICW) so the TBW/ECW and ECW/ICW trends can be determined as well as the phase angle ratio in diagnostic and prognostic terms.
This means that the BIA device alone is not suitable for following changes in body composition in conditions of particular clinical-nutritional interest so it also needs to be completed in conjunction with the rest of the nutritional status evaluation.
Morphogram Pro provides a complete nutritional status evaluation however it offers the ability to integrate the results from BIA to display the nutritional status from Morphogram with the intra and extracellular hydration data from BIA and provide a combined view on patient conditions.
