The variations of the maternal serum levels of cystine-aminopeptidase or oxytocinase (C.A.P.) have been studied in 399 measurements from 326 pregnant patients, 226 normal pregnancies were used as control and allowed us to set up a range of normal values for the age of pregnancy; the mean levels increase exponentially. It has not been possible from this study to establish conclusively a direct relationship between the C.A.P. levels, or variations of these levels and the onset of a fetal and/or placental pathology. In twin pregnancies only, the levels were constantly elevated.
