Beta-2 Microglobulin, B2M

MHC (Major Histocompability Complex) is a large locus on human DNA which code for surface proteins essential for the immune system. Beta-2 Microglobulin (BHC), is a component of MHC Class I molecules. As this molecule is found on the surface of many cells (excluding erythrocytes) of healthy peole who have very small amounts in their blood under normal condutions The test is mostly used as a tumor marker for bone marrow cancer, multiple myeloma, lymphoma and leukemia. If it is found in Cerebrospinal fluid, it means that the cancer has spread to the brain and/or spinal cord.
Interpretation: Low values are not interpretable but as this molecule is very low in the blood and body fluids its increase may be due to infection, inflammatory disorders, immune disorders or certain types of cancer.
