Tests for Lymphoedema

What tests are performed to confirm lymphoedema?

The Perometer (pictured below) is a very fast and easy way of measuring the volume of the limb. Within second the Perometer ring is slid up over the limb, and the exact dimensions are captured by the computer. This information not only allows us to keep an eye on how effective treatments are, but also to provide the most accurate way of getting the right stockings and bandages for our patients.
Sometimes tests would be performed to exclude other causes of leg swelling, for example, a scan of the veins in the leg (a duplex scan). Blood tests may be helpful in excluding other causes.

Often an isotope lymphogram or 'lymphoscintography' is used to confirm the diagnosis of lymphoedema. This test does not, however, show what type of abnormality is present, for example, too few lymphatics or a normal number of poorly functioning ones, but often this does not alter the management.

Very occasionally it is important to obtain a more detailed view of the lymphatics and this can be achieved with an operative lymphangiogram. A CT scan or pelvic ultrasound is sometimes performed when it is important to exclude a mass or lump in the pelvis or abdomen.
