The Beta-2 microglobulin looks at a marker used in myeloma and lymphoma. It is done for: staging and monitoring blood cancers.
General health information, not a diagnosis. In an emergency, call 102. Always consult a qualified health professional.
Beta-2 microglobulin is a marker used to assess the activity of blood cancers such as myeloma and lymphoma. It is typically measured to help stage and monitor these cancers. The test is not usually performed on an empty stomach. The results, which can be high or positive, indicate whether the disease is active or if there's kidney impairment. A low or negative result suggests normal kidney function. The test measures a marker specific to myeloma and lymphoma. The sample type is blood. If the result is high, it may indicate disease activity or kidney impairment. If the result is low, it suggests normal kidney function. Results should be interpreted by a qualified health professional.
