Prenatal screening and its utility or importance has got polarized opinions. While some feel it is the need of the hour, the other group is convinced of their complete inexpediency. Therefore we really need to look at the pros and cons that prenatal screening has on offer for pregnant women.
The doctors opine that prenatal screening in an ultrasound has no harmful effects and that the use of the latest and advanced equipment to conduct this test makes the test even more fail-safe. The various aspects which can be looked over with the help of ultrasound are:
- The number of embryos in the uterus and their viability are determined;
- Put a more accurate period of pregnancy;
- Gross defects are excluded;
- Determines the thickness of the collar space - (that is, the amount of subcutaneous fluid on the back of the child's neck is measured - in normal TVP should not exceed 2.7 mm);
- The presence or absence of the nasal bone is investigated.
However, there are quite a few arguments which make prenatal screening questionable to many. Many mothers are sure that it is impossible to make at least some reliable conclusions on one analysis- too many factors can affect the result. And, in part, they are really right. However, it is necessary to study the analysis process more closely in order to understand on what basis the doctor makes a conclusion. The second screening takes place at 18-21 weeks of pregnancy. This study includes a "triple" or "quadruple test”. The test follows the same step as in the first trimester- the woman again takes a blood test. Only in this case, the results of the analysis are used to determine not two, but three (or, respectively, four) indicators.
Some mothers point out strong heredity and don’t see a reason to go for ultrasound. There is a mindset which governs their judgement; all relatives are healthy, what problems could there be? Indeed, there are certain groups of women who are primarily recommended to undergo Pregnancy Ultrasound to identify possible pathologies in the development of a child. These are women over 35–40 years old (since after this age, the risk of developing abnormalities in a child increases several times) and expectant mothers with certain diseases (for example, diabetes).
