Distinguished levels take the role on electrophoresis as a sharp mountain top in the migration enclosure of the corresponding Ig extraction. Macroglobulins are monoclonal IgM in launching and restricted to only κ or λ light-chain group. The level of macroglobulins increases signifcantly in lympho- cytic and plasmolytic disorders such as multiple myeloma or leukemia. It also increases in some collagen diseases, reticu- losis, inveterate transmissible states, and carcinoma. Paraproteinemias are malignant diseases in which there is spread of a only clone of plasma cells producing monoclonal immunoglobulin.
