The immunoelectrophoretic patterns (IEP) of serum proteins of leprosy patients were studied. The β2M immunoglobulins were elevated in the sera of patients having the lepromatous type of leprosy but were not elevated in the sera of patients having the tuberculoid type of leprosy. These serum globulin changes may prove to be useful in differentiating these two types of leprosy.
