FIELD: medicine.
SUBSTANCE: method involves analysing peripheral blood to measure an anti-cytomegalovirus antibody titre in the first trimester of gestation, placental homogenate dehydroepiandrosteron sulphate when the patient is 12 weeks pregnant and peripheral blood dehydroepiandrosteron sulphate and oestriol. If the anti-cytomegalovirus antibody titre tends to increase to 1:1,600, placental homogenate dehydroepiandrosteron sulphate grows to 1.20 mcmole/l, and peripheral blood dehydroepiandrosteron sulphate decreases to 7.53 mcmole/l, and oestriol - to 2.70 pmole/l, a foetal development threat is stated.
EFFECT: higher accuracy of assessment.
