The
properties of the BIA circuit in the body are well defined. The method of
measurement is precise, sensitive, and specific in its ability to illustrate
specific changes inherent in the biological subject.
The BIA provides a scientific index - a 'snapshot' of cellular level dynamics
and architecture, giving valuable and immediate data of the individual?s state
of health and healing from many protocols including medical research, clinical
practice and the health care professional analysis and recommendation.
BIA prediction measurement equations have been developed since 1939. The
measurements use parallel resistance and reactance as predictors of
intracellular, extracellular and body cell mass. These equations can specify if
cellular health is static, progressing and/or regressing. (Comparisons to K40,
DEXA and D20 were very good (r > .9) and are sufficient to be used in clinical
practice and studies of wasting disorders in AIDS patients.[1])
