[Progressive antithrombin activity in blood of pregnant women and neonates in the first four days of life (author's transl)].

Abstract

Progressive antighrombin activity was assayed in 45 term infants in the first four days of life, in 20 cord blood specimens and in the blood of 20 pregnant women (at term). In the term infants a positive correlation was shown between progressive antithrombin and postnatal age. No correlation could be demonstrated with sex, ethnic group or type of delivery. Maternal antithrombin activity was shown to be moderately decreased, maternal values being closely related to cord blood values.
