Bence Jones proteins are present in 50–80% of people with multiple myeloma. People with other malignancies also can have a positive Bence Jones proteins test, but less frequently.
Certain nonmalignant diseases, such as rheumatoid arthritis, systemic lupus erythematosus, and chronic renal insufficiency, can have Bence Jones proteins in the urine. High doses of penicillin or aspirin before collecting the urine can give a false positive result.
