*Mechanism believed to be igE-mediated for high molecular weight compounds and for some low molecular weight compounds. The immunologic mechanism for many low molecular weight substances remains ~ind~ fined. (Adapted from M. Chan-Yeung, S. Lam, Occupational Asthma. Am Rev Respir Dis, 1986; I33:686-703.
