What does a positive Bence Jones test mean?

What does a positive Bence Jones test mean?

Bence Jones proteins are not normally found in urine, so a positive test indicates that you probably have multiple myeloma. Other kinds of cancer may also be associated with a positive result. An abnormal test may indicate other types of cancer including lymphoma, chronic lymphocytic leukemia, and macroglobulinemia.

Is serum protein elevated in multiple myeloma?

Myeloma protein (M-protein) is a gamma globulin. If the myeloma cells are making M-protein, the amount of globulin in the blood rises, which results in elevated total protein. At diagnosis, elevated total protein should prompt your doctor to order more specific tests to see if you have myeloma.

What blood test indicates multiple myeloma?

The CBC is both a basic test done during every medical check-up. It is one of the most important blood tests used for diagnosing and monitoring myeloma patients. The CBC quantifies all the cells that make up the solid parts of blood. The liquid part of blood that is colorless is called serum.

How do you confirm the presence of Bence Jones proteins?

Bence-Jones proteins are not detectable via urine protein dipsticks. Detection of Bence-Jones proteinuria requires sophisticated tests such as urine protein electrophoresis, immunoelectrophoresis, and immunofixation electrophoresis. The screening test most commonly used is urine protein electrophoresis.

What happens if serum protein is high?

High total protein: Too much protein in your blood can be a sign of chronic infection or inflammation (like HIV/AIDS or viral hepatitis). It can also be an early sign of a bone marrow disorder. Low A/G ratio: This might be the sign an autoimmune disorder, where your body’s immune system attacks healthy cells.

How do you test for M protein in blood?

How do you test for M proteins?

1. A complete blood count (CBC). This blood test measures the levels of different cells in your blood and can reveal certain MGUS-related issues such as anemia.
2. Beta-2 microglobulin test.
3. Biopsies.
4. Blood chemistry tests.
5. Echocardiogram (ECHO).
6. Imaging tests.
7. Urine protein tests.
