The determination of oxytocinasemia is the method of choice in monitoring multiple pregnancy. An increase in the level of the enzyme indicates a normal development of the pregnancy.

Although, as a rule, the oxytocinasemia level is higher in multiple than in single pregnancy, there are cases with a level pointing to intrauterine fetal danger, if, in a gestation beyond the seventh lunar month, it is lower than 4 μmol∣l∣min.

The birth of a newborn with a body weight below 2500 g, when the oxytocinasemia level exceeds 12 I.U., indicates that a multiple pregnancy is involved.
