The GP may refer you to a specialist lymphoedema treatment centre for further assessment.

In most cases, further tests are not necessary, but they may occasionally be used to assess and monitor your condition.

Measuring limb volume

These may include:

Bioimpedance testing

During a bioimpedance test, small metallic discs called electrodes are placed on different parts of your body.

The electrodes release a small, painless electric charge that's measured using a handheld device. Changes in the strength of the current can indicate the presence of fluid in your tissue.

Imaging tests

Imaging tests may also be used to help diagnose and monitor lymphoedema.

These include:

These scans can be used to create a clearer picture of the affected tissue.
