What is the difference between ultrasound and screening during pregnancy
Women who are carrying a child are assigned a lot of research, the meaning of which they do not understand. Therefore, it is worthwhile to figure out how ultrasound differs from screening and what are the benefits of these procedures for the health of the expectant mother and baby.
Why is pregnancy research needed?
Ultrasound is a common diagnostic method that is often prescribed for expectant mothers. Thanks to this study, the gynecologist visually observes the baby while he is in the womb. For the entire period of bearing a child, a woman is prescribed at least three such procedures. But if pathologies are identified, then ultrasound studies are carried out more often.
Ultrasound from screening differs in research tasks
The first ultrasound is performed when the mother is registered. Thanks to the procedure, the doctor can judge the timing and degree of development of the embryo. But ultrasound examination does not reveal chromosomal abnormalities of the fetus, but assesses its external structure. And to find out if the baby has genetic diseases, perinatal screening is carried out.
This term assumes a whole complex of examinations, including a biochemical blood test and ultrasound. Thanks to them, even in the early stages, the risk of developing serious genetic diseases in the fetus, such as Down syndrome, Edwards syndrome and others, is revealed.
Screening is mandatory at 10-13 weeks and 20-22 weeks
The main purpose of the examinations is to identify markers of chromosomal abnormalities in the embryo. But also during the examination, the condition of the uterus, placenta and amniotic fluid is assessed. If there is a pathology, the woman is assigned additional consultations with a geneticist. And additional screening is also carried out at 30-32 weeks.
What is the difference between screening and ultrasound?
Perinatal screening is carried out like a conventional ultrasound scan, and no additional manipulations are done during this examination. But these studies have different goals. Screening identifies all possible anomalies in the baby’s development. Ultrasound is an examination that shows the health status of the mother rather than the child.
Screening, like ultrasound, is a safe procedure that does not involve radiation. So don’t be afraid to do these surveys.
Screening is an important study that cannot be discarded. Thanks to this diagnostic method, it is possible to see chromosomal abnormalities in the development of the fetus even in the early stages, when it is still possible to terminate the pregnancy. And ultrasound shows the external state of the embryo, and also helps to monitor the health of the mother.
