&lt;h2&gt;&lt;span style=&quot;color: #33cccc;&quot;&gt;&lt;strong&gt;Overview&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span style=&quot;color: #808080;&quot;&gt;Beta-2-microglobulin (beta-2-M) evaluation is valuable for assessing central nervous system inflammation and B-cell proliferative diseases. This small membrane protein, found on the surface of all nucleated cells, is associated with class I major histocompatibility complex proteins. Elevated levels of beta-2-M in cerebrospinal fluid (CSF) can aid in diagnosing conditions such as non-Hodgkin lymphoma with central nervous system involvement and aseptic meningoencephalitis, indicating potential neurologic processes like HIV infection and acute lymphoblastic leukemia. However, its utility in multiple sclerosis diagnosis remains uncertain.&lt;/span&gt;&lt;/p&gt;
