All patients with symptoms of restless legs syndrome (RLS) should be tested for iron deficiency. [3, 4] At a minimum, a ferritin level should be obtained. A complete iron panel, including iron levels, ferritin, transferrin saturation, and total iron binding capacity, is preferable because the ferritin level can be falsely elevated in acute inflammatory states.
