The Bence Jones protein (BJP) test measures the level of BJP in your urine. Bence Jones proteins are named for Henry Bence Jones, a physician and chemist who first isolated them in 1847. These proteins are not present in healthy urine samples and are usually a sign of multiple myeloma.
BJP test is necessary to diagnose multiple myeloma.
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.
