What does an L-Dex value of 10, 20 or 30 mean?
The lymphedema index (L-Dex) defines the normal range for a patient without lymphedema. L-Dex values greater than 10 are outside the normal range and are indicative of lymphedema. An L-Dex value of 20 puts a patient approximately two times outside the normal range and likewise, 30 is approximately 3 times outside the normal range. Note: L-DexTM values that lie outside the normal range may indicate the early signs of lymphedema and values that have changed +10 L-Dex units from baseline may also indicate early lymphedema. The L-Dex scale is a tool to assist in the clinical assessment of lymphedema by a medical provider. The L-Dex scale is not intended to diagnose or predict lymphedema of an extremity.
