The test is ordered during the initial work-up of a patient that has multiple myeloma. The test helps stage the disease and also evaluates the degree of activity of cancer. It also aids in gauging the effectiveness of treatment. It also aids in charting the prognosis. If interference with the nervous system is suspected, a CSF B2M may be ordered. In terms of kidney disease, if an individual is showing symptoms of kidney dysfunction, the test may be ordered. Signs include:
- Swelling or puffiness, especially near the eyes or in the face, wrists, or ankles
- Foamy, bloody, pink, or brownish urine
- Protein in the urine
- Fatigue and weakness
A urine B2M test is ordered to monitor patients who have had a kidney transplant or have been exposed to cadmium. Patients on dialysis might be directed to get it done to test for DRA, where excess B2M is found in the blood and the osteoarticular structure.
