The SOZO device uses bioimpedance spectroscopy (BIS) to monitor and measure for lymphoedema and body composition. Bioimpedance refers to the process of sending a painless electrical current through the body. This process detects information regarding your fluid and tissue status.

To screen for lymphoedema the client removes their shoes and socks and any heavy jewelry, then stand on the device. The screening takes 30 seconds

Those who have a pacemaker and during pregnancy cannot have the service.
