Overview of the Bence-Jones Protein
The Bence-Jones Protein test is a specialist urine investigation used to detect monoclonal immunoglobulin free light chains excreted into urine.
Immunoglobulins are antibodies composed of heavy and light chains. Plasma cells normally produce small quantities of light chains, but abnormal plasma-cell clones can produce substantially increased amounts of a single light-chain type.
These excess light chains can circulate in the blood and pass through the kidneys into the urine.
The test contains 1 biomarker: Bence-Jones Protein.
Bence-Jones proteins are classically associated with plasma-cell disorders including multiple myeloma, light-chain myeloma and related monoclonal gammopathies.
However, the test does not diagnose multiple myeloma by itself.
Modern investigation of suspected plasma-cell disease frequently combines urine testing with serum protein electrophoresis, immunoglobulins and serum free light chains.
Bence-Jones proteins can also contribute to kidney injury when produced in substantial quantities.
The sample may be a random urine specimen or a timed urine collection depending on laboratory and clinical requirements.
What Does the Bence-Jones Protein Test Check?
This test measures 1 biomarker.
Bence-Jones Protein
Detects monoclonal immunoglobulin free light chains excreted in urine. Detection can support investigation and monitoring of plasma-cell disorders but requires correlation with serum protein studies and clinical findings.
Who May Benefit From the Bence-Jones Protein Test?
This test may be suitable where a plasma-cell disorder or monoclonal protein abnormality is being investigated.
People being investigated for multiple myeloma - Bence-Jones proteins can be produced by abnormal plasma-cell clones.
People with unexplained monoclonal protein findings - Urine analysis may complement serum investigations.
People with unexplained bone pain - Plasma-cell disorders can affect bone, although bone pain has many more common causes.
People with unexplained anaemia - Anaemia may occur in myeloma and other haematological conditions.
People with unexplained kidney impairment - Free light chains can contribute to renal injury.
People with recurrent infections and abnormal protein results - Plasma-cell disease may alter normal immunoglobulin production.
People with high calcium alongside other concerning findings - Hypercalcaemia may occur in advanced plasma-cell disorders.
People with known plasma-cell disease undergoing monitoring - Repeat testing may form part of specialist follow-up.
Specialist-requested urine protein testing - The test can be arranged when requested by a haematologist, oncologist or GP.
How to Prepare
An incomplete timed urine collection can affect quantitative interpretation.
Do not substantially alter fluid intake simply to change the concentration of the urine sample.
Symptoms and Reasons to Consider the Bence-Jones Protein Test
Bence-Jones Protein testing is generally considered because of a wider clinical or laboratory pattern rather than one specific symptom.
Persistent unexplained bone pain - Myeloma can affect the skeleton but bone pain has many alternative causes.
Unexplained anaemia or fatigue - Bone marrow disorders can impair normal red blood cell production.
Kidney impairment without a clear cause - Excess free light chains can damage renal structures.
Recurrent infections - Abnormal plasma-cell activity can interfere with normal antibody production.
Unexplained high calcium - Increased bone turnover can contribute to hypercalcaemia in selected plasma-cell disorders.
Abnormal total protein or globulin - Unexpected protein abnormalities may lead to electrophoresis and light-chain assessment.
Previously identified monoclonal gammopathy - Urine testing may form part of specialist assessment or monitoring.
These symptoms do not mean that multiple myeloma is present.
A positive Bence-Jones Protein result requires additional assessment, while a negative urine result does not exclude every plasma-cell disorder.
Severe bone pain, acute kidney deterioration, confusion associated with marked hypercalcaemia or serious systemic illness requires prompt medical assessment.

When Will I Receive My Results?
The expected turnaround time for the Bence-Jones Protein test is approximately 2 business days after the laboratory receives your sample.
Additional protein characterisation may occasionally extend reporting.
Understanding Your Results
A negative result means significant Bence-Jones Protein was not detected using the laboratory method employed.
This reduces the likelihood of substantial urinary monoclonal free light-chain excretion but does not exclude all plasma-cell disorders.
A positive result means monoclonal free light chains have been detected in urine.
This finding can occur in multiple myeloma and related monoclonal plasma-cell disorders.
Further investigation commonly includes serum free light chains, protein electrophoresis, immunoglobulins, Full Blood Count, calcium and kidney function.
The result should be reviewed by an appropriately qualified clinician rather than interpreted as a cancer diagnosis by itself.
