[Trial of immunodiffusion on cellulose acetate. Application to the estimation of immunoglobulins A and serum transferrin. Results in alcoholism and cirrhosis (author's transl)].

The authors propose electro-immunodiffusion on cellulose acetate instead of agar gel. This simple, rapid and economical method was applied to the estimation of serum immunoglobulins A and transferrin. The following results were obtained for the IgA/transferrin ratio in 108 cases: Normal: 0.87 +/- 0.29; alcoholics without proved cirrhosis: 1.61 +/- 0.95; alcoholic cirrhosis: 3.36 +/- 2.30. The interest of this determination in detection is increased by this simple test.
