| IgA class reticulin antibodies are found in dermatitis herpetiformis (25%) and celiac disease (60%), but not in other autoimmune problems. IgG class reticulin antibodies are found in other disease states, especially bullous dermatoses, and sometimes in normal patients. All positives are titered to endpoint. If Reticulin Antibody is 1:5, then a titer will be added. |
