Test Details

Test Includes

β2 microglobulin, serial monitor report; lipid-associated sialic acid (LASA), serial monitor report


β2-microglobulin is increased nonspecifically in active chronic lymphocytic leukemia (CLL) due to increased lymphocyte turnover.


This profile is not useful as a screening or diagnostic test for leukemia or lymphoma.

The LASA test may be considered by Medicare and other carriers as investigational and, therefore, may not be payable as a covered benefit for patients.


See individual tests.

Additional Information

β2-microglobulin is a cell membrane associated 100 amino acid peptide, a component of the lymphocyte HLA complex. It is increased nonspecifically in inflammatory reactions and in active chronic lymphocytic leukemia in which there is increased lymphocyte turnover.
