[Determination of serum transcortin levels by electroimmunodiffusion (author's transl)].

The isolation of transcortin in a pure form made possible the preparation of a monospecific anti-human transcortin rabbit serum. Serum transcortin levels were measured by electroimmunodiffusion. Experimental results expressed as errors by the calculating of interserial reproducibility were 4.74 per 100. The mean value was significantly different for men (36 subjects: 39.7 +/- 3.6 mg/l) from women (36 subjects: 42.1 +/- 3.9 mg/l). The transcortin determination was performed in pregnancy serum and in serum of women during oestroprogestative treatment. Some studies were performed in pathological cases (hyper- and hyperthyroidism, hyper- and hypocorticism, Kahler disease, ascitic cirrhosis).
