SOZO
Bioimpedence Spectroscopy (BIS)

A quick, painless scan that measures fluid levels in your body, helping us detect and monitor swelling early so we can guide timely, personalised care and keep you feeling confident and in control.

What is a SOZO Bioimpedence Spectroscopy (BIS) ?

SOZO is a clinically validated device that uses Bioimpedance Spectroscopy (BIS) to measure fluid levels in your limbs.

Bioimpedance Spectroscopy works by sending a very low-level, painless electrical signal through the body. The device then measures how the signal travels through different tissues. Because fluid conducts electricity differently to fat and muscle, the system can detect small changes in extracellular fluid levels.

This provides an objective measurement of lymphatic fluid and helps identify early lymphatic changes — often before swelling becomes noticeable.

SOZO is commonly used for:

Early detection of lymphoedema (particularly following cancer treatment)
Ongoing monitoring of known lymphoedema
Tracking response to treatment
Establishing a baseline before surgery or radiation
Long-term survivorship screening

What to Expect During Your Assessment

A SOZO scan is quick, simple, and completely painless. It can be performed as a standalone screening appointment or incorporated into your comprehensive assessment.

During the test:

You will remove your shoes and socks.
You will stand barefoot on the device and lightly hold the hand electrodes.
The scan takes approximately 30 seconds.
You will not feel the electrical signal.

The device generates a reading (commonly known as an L-Dex score in lymphoedema monitoring), which we interpret alongside your symptoms and physical findings.

When included as part of your oedema, lymphoedema, or lipoedema assessment, SOZO provides additional objective data to complement:

Circumference measurements
Tissue texture assessment
Symptom history
Clinical examination

For individuals with lipoedema, SOZO helps determine whether fluid accumulation is present alongside fat tissue changes. For those with oedema or lymphoedema, it assists in detecting early fluid shifts and monitoring treatment progress.

There are no needles, no radiation, and no discomfort.

Who Should Consider a SOZO Assessment?

SOZO screening may be beneficial if you:

1 / People Who Have Had Lymph Nodes Removed

Lymph node removal can reduce your body’s ability to drain fluid. This increases the risk of lymphoedema. Regular SOZO scans help detect fluid changes early, often before swelling appears.

2 / People Who Have Had Radiation Therapy

Radiation can cause scarring in lymphatic vessels. These changes may affect fluid movement over time. SOZO helps monitor for early shifts in fluid levels.

3 / People Who Have Had Cancer Treatment Involving Lymph Nodes

Treatments for breast, gynaecological, melanoma, prostate and other cancers may impact lymphatic function. A baseline reading allows for accurate comparison over time. Ongoing scans support early detection.

4 / People with Diagnosed Lymphoedema

SOZO provides objective data to track fluid levels. It helps monitor treatment response. It can also identify early signs of flare-ups.

5 / People with Persistent or Unexplained Swelling

If you have ongoing swelling, SOZO can help determine whether fluid accumulation is present. It supports clinical assessment and treatment planning.

6 / People with Lipoedema

SOZO can identify whether fluid is present alongside fat tissue changes. This helps detect lipo-lymphoedema and guides management decisions.

7 / People Wanting Preventative Screening

A baseline scan provides a reference point for the future. Subtle changes can then be detected earlier.

8 / People Receiving Lymphatic or Oedema Treatment

SOZO can measure progress during treatment. It provides clear, trackable data to guide care.

Accurate, Safe, and
Evidence-Based Monitoring

SOZO Bioimpedance Spectroscopy enhances your clinical assessment by providing measurable, trackable data. It does not replace hands-on evaluation but strengthens our ability to detect and manage fluid-related conditions early and effectively.

If you are experiencing swelling, are at risk of lymphoedema, or would like proactive monitoring as part of your assessment, SOZO screening can be included in your appointment to provide deeper insight into your lymphatic health.

Body Composition on the SOZO

Yes , you read correctly our SOZO machine also completes a body Composition scan. A body composition analysis gives a quick glimpse of your health. It accurately measures and tracks changes in fluid, tissue, and metabolic changes over time which can help you identify areas you need to work on to lower your risk of disease, improve your overall health, and can provide valuable insight to disease progression as well.

A single SOZO measurement provides specific measurements of:
