(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.

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.

bioelectrical impedance analysis

whole-body conductivity method for assessing body composition. A small alternating current flowing between two electrodes passes more rapidly through hydrated fat-free body tissues and extracellular water than through fat or bone because of the greater electrolyte content (lower electrical resistance) of the fat-free component. Impedance to electric current flow can be related to total body water content and in turn to fat-free mass, body density and percentage body fat.
