Quantitative Bence-Jones protein test

What is Quantitative Bence-Jones Protein Test?

The Quantitative Bence-Jones Protein test is a medical test to measure levels of immunoglobulin-related light chain proteins in the urine. It is used in the diagnosis and monitoring of multiple myeloma, a type of blood cancer. It is also referred to as serum Bence-Jones protein test and urine Bence-Jones protein test.

Why is the Quantitative Bence-Jones Protein Test Done?

The purpose of this test is to measure the amount of light chains, usually immunoglobulin (Ig) light chains, present in the urine. This test helps in diagnosing multiple myeloma, a condition in which abnormal amounts of light chains are present in the bloodstream or urine. It is also used in monitoring the disease and to determine treatment effectiveness.

Preparation for a Quantitative Bence-Jones Protein Test

A Quantitative Bence-Jones Protein test does not involve any specific preparation. However, patients are advised to inform their doctor about any medications and supplements they are taking, as some of them can interfere with the test.

Procedure for a Quantitative Bence-Jones Protein Test

This test is usually done through a urine sample. A healthcare professional will collect a sample of the patient’s urine and send it to a laboratory for analysis. The laboratory will examine the sample for the presence of Ig light chain proteins.

Types of Quantitative Bence-Jones Protein Tests

There are two types of Quantitative Bence-Jones Protein Tests - qualitative and quantitative. Qualitative tests are used to determine whether Igs are present in the urine, while quantitative tests measure the amount of Igs that are present.

Risks Associated with Quantitative Bence-Jones Protein Test

A Quantitative Bence-Jones Protein test is a safe and routine procedure that does not involve any risks.

When is the Quantitative Bence-Jones Protein Test Suggested?

The Quantitative Bence-Jones Protein test is recommended for people who are suspected to have multiple myeloma or for those who have been diagnosed with the condition. It can also help in the monitoring and evaluation of treatment efficacy.
