Bence Jones Protein, Urine (Qualitative)

Understanding Bence Jones Protein, Urine (Qualitative)

Bence Jones proteins, also known as BJ proteins, are composed of light chains (either kappa or lambda) produced by plasma cells. Normally, plasma cells secrete antibodies in the form of immunoglobulins, which are composed of both heavy and light chains. However, in some health conditions, like multiple myeloma, the plasma cells begin to synthesize an excessive amount of light chain that enters the blood. Some of these free light chains are filtered via the kidneys and excreted into the urine, where they are known a...

What does Bence Jones Protein, Urine (Qualitative) measure?

The Bence Jones Protein, Urine (Qualitative) test examines the presence of abnormal plasma cell proteins called Bence Jones proteins in the urine sample. This test aids in diagnosing and managing plasma cell disorders such as multiple myeloma, evaluating kidney health, and monitoring treatment response.
