A, Titers of of trimellitic anhydride (TMA)-specific antibody classes (sIgG, sIgE, sIgG4) in TMA-exposed workers in high exposure areas (levels 3 and 4). B, Diagrammatic representation of average TMA-specific antibody profiles of active and removed workers. Removed workers manifest significantly higher average sIgG and sIgE values compared to actively exposed workers. sIgE values were expressed in kU/L, while specific IgG and specific IgG4 values were expressed in lg/mL. *Two workers in the actively exposed area with borderline sIgE were reassigned to lower exposure areas
