What Is an Immunofixation Electrophoresis Urine Test?
The immunofixation electrophoresis urine test is a specialised laboratory test that identifies abnormal proteins in urine. It uses an electric current to separate proteins in the sample, then applies specific antibodies to reveal any unusual protein patterns. Doctors may order this test when they suspect a condition affecting plasma cells, a type of white blood cell. It is also known as Urine IFE, UIFE, or the Bence Jones Protein Test.
What Does an Immunofixation Electrophoresis Urine Test Measure?
The immunofixation electrophoresis test analyses several proteins that are excreted in urine. Abnormal levels or patterns can point to specific disorders involving plasma cells.
Here is a brief overview of the key components analysed:
| Component | What It Is |
|---|---|
| Monoclonal protein (M-protein) | An abnormal protein produced by a single type of plasma cell; not normally present in urine |
| Immunoglobulins (IgG, IgA, IgM) | Antibodies made by plasma cells; abnormal levels may point to a plasma cell disorder |
| Kappa (κ) free light chains | One type of protein fragment produced by plasma cells; excess amounts may suggest abnormal cell activity |
| Lambda (λ) free light chains | The other type of protein fragment, an imbalanced ratio with kappa chains, can indicate a disorder |
| Bence Jones proteins | Free light chain proteins that, because of their small size, pass through the kidneys into the urine; their detection is a significant diagnostic marker |
Why Is an Immunofixation Electrophoresis Urine Test Done?
Doctors request this test for a range of clinical reasons, from initial investigation of suspicious symptoms to ongoing monitoring of known conditions.
Common Symptoms That May Require This Test
Your doctor may recommend the immunofixation electrophoresis urine test if you are experiencing any of the following:
- Persistent bone pain, particularly in the back or ribs
- Unexplained fatigue or weakness
- Frequent or recurring infections
- Numbness or weakness in the arms or legs
- Unexplained weight loss
- Broken bones from minor activities
- Excessive thirst
Conditions This Test Can Help Detect
This test can help identify several conditions related to abnormal protein production. These include:
- Multiple myeloma, a type of blood cancer affecting plasma cells
- Waldenström's macroglobuniaemia, a rare lymphoma involving B-cells
- Monoclonal gammopathy of undetermined significance (MGUS), where plasma cells produce excess antibodies without forming a tumour
- Amyloidosis, a condition where abnormal protein deposits collect in organs
- Chronic lymphocytic leukaemia
- Light chain deposition disease
- Renal (kidney) disorders involving free monoclonal immunoglobulin light chains
Immunofixation Electrophoresis Urine Test for Chronic Disease Monitoring
The urine immunofixation electrophoresis test plays an important role in monitoring known plasma cell disorders over time. It is recommended at regular intervals following a diagnosis of smouldering myeloma, typically at 2 to 3 months after diagnosis, then every 4 to 6 months for the first year, and every 6 to 12 months if results remain stable. A reduction or disappearance of monoclonal protein after treatment may indicate a response to therapy, while persistent levels may signal that the disease is not responding.
How to Prepare and What to Expect
Preparation for this test is straightforward. The main requirement is collecting your urine carefully over a 24-hour period.
Do You Need to Fast?
No fasting is required before this test. You can eat and drink normally throughout the collection period.
Practical Tips Before Your Test
A little preparation helps ensure the sample is collected correctly. Keep the following in mind:
- Bring a detailed clinical history including your symptoms, previous test results and family history, as this is required for the test
- Inform your doctor about all medicines, vitamins, supplements and herbal remedies you are taking
- Stay well hydrated during the 24-hour collection period
- Avoid strenuous physical activity for 24 hours before and during the collection
- Store the collection container in a refrigerator throughout the collection period
Step-by-Step Procedure
The immunofixation electrophoresis test procedure involves collecting urine over a full 24-hour period. Here is what to expect:
- On the morning of the collection day, empty your bladder completely and do not collect this first sample. Note the exact time.
- From this point, collect all urine passed over the next 24 hours into the sterile container provided.
- Store the container in a refrigerator or cool place throughout the collection period.
- At the end of 24 hours, empty your bladder one final time into the container.
- Label the container as instructed and keep it refrigerated until handover.
- Submit the full container to the laboratory or hand it to the home collection professional as instructed.
- The sample is transported under refrigeration and processed at an NABL-accredited laboratory using gel electrophoresis.
Factors That Can Affect Accuracy
Certain factors may affect the reliability of your results. Be aware of the following:
- Dehydration during the collection period
- Incomplete or improper 24-hour urine collection
- Certain medications that interfere with protein levels
- Pre-existing kidney disease, which can alter free light chain levels
- Use of preservatives in the collection container
- High levels of polyclonal free light chains, which may complicate interpretation
Understanding Your Immunofixation Electrophoresis Urine Test Results
Results from this test require careful interpretation by a qualified doctor, as several factors influence what the findings mean for each individual. The table below shows general reference values.
| Parameter | Normal Range | Unit |
|---|---|---|
| Monoclonal protein | Not detected / Negative | — |
| Kappa free light chains | 3.3 to 19.4 | mg/L |
| Lambda free light chains | 5.7 to 26.3 | mg/L |
| Kappa/Lambda free light chain ratio | 0.26 to 1.65 | Ratio |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain health conditions can influence how results are interpreted:
- In patients with chronic kidney disease, the free light chain ratio may fall outside the normal range even without a plasma cell disorder. This occurs because the kidneys normally clear free light chains from the blood, and impaired kidney function can distort the ratio. Doctors typically apply adjusted reference ranges in such cases.
- Conditions such as chronic infections, autoimmune diseases, liver disease and inflammation may also cause the free light chain ratio to shift outside the standard reference range. Your doctor will consider these factors when reviewing your results.
How to Maintain Healthy Levels
While this test identifies specific medical conditions rather than lifestyle-related markers, these general habits support your overall health:
- Attend regular health check-ups, particularly if you are above 40 or have risk factors for plasma cell disorders or a family history of blood cancers
- Stay well hydrated daily to support kidney function
- Report any unexplained bone pain, persistent fatigue or frequent infections to your doctor promptly

Frequently Asked Questions
Both tests detect abnormal proteins, but they analyse different samples. The urine test specifically identifies Bence Jones proteins (free light chains) excreted by the kidneys, while the serum version detects monoclonal proteins circulating in the blood. Both are often ordered together to give doctors a complete picture.
Protein levels in urine can vary at different times of the day. A 24-hour collection captures these fluctuations and gives a more accurate measure of the total amount of protein being excreted. This helps doctors quantify Bence Jones protein levels more reliably.
No. Standard urine dipstick tests only detect albumin, which is a different type of protein. Bence Jones proteins require specialised methods such as the immunofixation electrophoresis urine test or serum free light chain assays to be identified.
A negative result means no monoclonal protein was detected in the urine, which is generally a normal finding. However, very low protein levels or non-secretory forms of certain diseases may not always be picked up. Your doctor will assess the result alongside your symptoms and other tests.
Yes, it can. The kidneys normally clear free light chains from the bloodstream. When kidney function is reduced, these proteins may accumulate or be excreted differently, which can alter the light chain ratio. Your doctor will account for this when interpreting your results.
Frequency depends on your individual condition. As a general guide, the test is typically repeated 2 to 3 months after a myeloma diagnosis, then every 4 to 6 months for the first year, and every 6 to 12 months if results remain stable. Your treating doctor will set the schedule that is right for you.
No. The immunofixation electrophoresis urine test procedure is entirely non-invasive. It only involves collecting your own urine over 24 hours at home, which is painless and carries no known risks.
