Why Get Tested?
Beta-2 microglobulin (B2M) is not a frequently requested test in the UK, however it may be used to detect and localise kidney damage and follow kidney disorders.
When to Get Tested?
The test is rarely requested when investigating kidney disease due to poor specificity. However it may be requested when you have symptoms and signs associated with kidney dysfunction; due to possible cadmium kidney toxicity. However the main use of B2M in the UK is in multiple myeloma (see the Beta-2 Microglobulin Tumour Marker article) not in kidney disease.
