Serum group‐specific components and transferrins of 24 pairs of mother‐fetal samples were studied. The results indicate that the human fetus is able to synthesize its own group‐specific components as early as the 10th to 13th week of gestation. A transferrin pattern different from the mother's could be demonstrated in the sera of two fetuses of about 9 and 21 weeks. Other fetuses showed transferrin qualitatively identical with the mother's. The concentration of fetal transferrins was greatly reduced.
