Another way to detect lymphedema

Bioimpedance spectroscopy (BIS) is a noninvasive technology that measures the amount of fluid in a limb. It works by sending low level electrical current through the arm or leg and measuring the resistance to current (impedance).

Electric current

Electric current is the rate of flow of electric charge. The electric charge that flows is carried by, for example, mobile electrons in a conductor, ions in an electrolyte or both in a plasma.

The SI unit of electric current intensity is the ampere. Electric current is measured using an ammeter.
