How is lymphedema measured today?

Unfortunately, most lymphedema is not detected until the arm has become visibly
swollen. By this time, in some cases, the condition is irreversible.

Once diagnosed, lymphedema is monitored during therapy by either a tape measure or other devices which estimate the total volume of the arm.

However, the good news is that there is new, FDA-cleared, technology called low frequency impedance which helps a medical provider to clinically assess and treat the onset of lymphedema earlier and to clinically monitor therapy more closely^3,4,5.

Low frequency impedance can detect increased fluid levels before visible swelling.
