Definition
Beta2-microglobulin is a protein found on the surface of many cells. Testing is done primarily when evaluating a person for certain kinds of cancer affecting white blood cells including chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and multiple myeloma or kidney disease.
Description
Testing methods vary, but most involve adding the person's serum—the yellow, liquid part of blood—or urine to one or more substances that bind to beta2-microglobulin in the serum or urine. The amount of the substance(s) bound to beta2-microglobulin is measured and the original amount of beta2-microglobulin is determined.
The test is covered by insurance when medically necessary. Results are usually available the next day.
