(BIA) (bī'ō-ĕ-lek'tri-kăl im-pē'dăns ă-nal'i-sis)
Method of determining body fat, fat-free body mass, and total body water by measuring resistance to the flow of a small electrical current passed through the body.

bioelectrical impedance analysis

(bī″ō-ĭ-lĕk′trĭ-kĭl),

BIA

A method of body composition analysis useful in measuring the total body water and other components. BIA relies on the changes in electrical current as it travels through body fluids and tissues. The results obtained may vary with ambient temperature and humidity, the subject's hydration, and other variables.
