Prenatal diagnostics is a complex of examinations of a woman and a foetus at different stages of pregnancy. It allows to detect abnormalities in the foetal development in the early stage, the risks of complications of pregnancy and birth complications.
Prenatal diagnostics allows to identify foetuses with Down’s syndrome, Edwards’ syndrome, Patau’s syndrome, as well as more than 40 % of problems in the development of internal organs and systems in the early stages of pregnancy.
The aim of prenatal diagnostics is timely diagnostics of foetal abnormalities and complications of pregnancy.
Methods of prenatal diagnostics
The main methods of prenatal diagnostics are biochemical blood tests and ultrasound examinations of a pregnant woman. When detecting a pathology and more accurate diagnostics is required, invasive methods are used.
Expert ultrasound examination allows to confirm the pregnancy at the early stages, detect an extrauterine pregnancy, determine the foetus age and the peculiarities of its development, find out the sex of an unborn child, detect pathologies, the risk of complications in pregnancy and birth complications.
In addition to the ultrasound examination, analysis of some indicators of the mother’s blood are carried out. The comprehensive processing of data received allows estimating the risks of chromosomal pathologies of the foetus, certain foetal abnormalities, as well as the risks associated with pregnancy complications such as foetal growth retardation, pre-eclampsia, premature birth, hypamnion, hydramnion, etc.
When and what examinations should be carried out?
In the first trimester at 11-13 weeks, complete examination of a pregnant woman and a foetus is performed. During this period, it is possible to eliminate severe foetal abnormalities, assess the risk of chromosomal pathology and obstetric complications. Risk assessment and ultrasound examination are not the direct foetal chromosomal analysis but they help to identify up to 95 % of chromosomal abnormalities if performed correctly.
In the second trimester at 19-21 weeks, a detailed foetal anatomy scan, control of its growth, evaluation of placental state and the state of amniotic fluid, cervix and blood flow in uterine arteries are performed. By analysing maternal blood, the risk of neural tube defects in the foetus (spina bifida, etc.) is detected.
In the third trimester, the growth and state of the foetus is controlled, the development of its organs is evaluated, abnormalities which do not occur at the earlier stages are excluded.
Prenatal diagnostics allows avoiding severe foetal pathologies, evaluate the state of the expecting mother, carry out prevention of pregnancy complications and be prepared for labour.
