How do you test for Bence Jones protein?
If your healthcare provider uses a test strip to look for Bence-Jones proteins, the strip may not detect them. The best way to find these proteins is to use electrophoresis or an immunoassay. Also talk with your healthcare provider to find out if any of the medicines you are taking might affect your test results.
What is the indication when you have positive result for Bence Jones protein determination?
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.
Which protein test does not detect Bence Jones?
Healthy urine does not contain Bence Jones protein, so its presence is an indication of a health problem. Other names for this test include urine protein electrophoresis (UPEP), urine immunofixation electrophoresis, or immunoassay for free light chains.
What is Bence Jones proteinuria associated with?
Chronic Idiopathic Bence Jones Proteinuria (first reported in 1982) is an asymptomatic plasma cell proliferative disorder that is associated with a risk of progression to symptomatic multiple myeloma (MM) or primary amyloidosis (AL).
Can myeloma be detected in urine test?
Urine tests A routine urine sample is typically taken to look for myeloma protein that has filtered through the kidney. You most likely also will be asked to give a sample of urine that has been collected over a 24-hour period, so it can measure how much myeloma protein is present.
What are abnormal results in a Bence Jones protein test?
The Bence-Jones protein urine test is used most often to diagnose and check on multiple myeloma, a type of cancer. Or an abnormal Bence-Jones test result may mean you have a type of malignant lymphoma. These are cancers of the lymphatic system. Multiple myeloma is a type of blood cancer that affects plasma cells.
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.
How long does a Bence Jones protein test take?
It can take anywhere from a few days to two weeks to get your results, depending on the lab and your doctor. Bence Jones proteins are not normally found in urine, so a positive test indicates that you probably have multiple myeloma.
What are Bence Jones proteins identical to?
A protein called the Bence-Jones protein, which is found in the urine of patients suffering from myeloma tumours, is identical with the L chains of the myeloma protein. Each patient has a different Bence-Jones protein; no two of the more than 100 Bence-Jones proteins that have been analyzed thus far are identical.
