[Immunological and oxidase measurement of ceruloplasmin in pregnant women and newborn (author's transl)].

Ceruloplasmin measurements were made by oxidase and immunochemical methods in serum from three groups of people, normal, pregnant women and their newborns. Whatever the method ceruloplasmin showed a decrease in the newborns and an increase in pregnant women as compared with the normal controls. The three groups showed a significant correlation between both measurement. The correlation ratio between the two methods of measurement in the newborns is significantly different from the pregnant and the normal groups. It appears that ceruloplasmin in the newborns' serum has a lower oxidase activity per molecule than that from adult's serum.
