A pregnant woman is obliged to monitor her health, do gymnastics, eat right and walk a lot in the fresh air. Also during pregnancy, absolutely all representatives of the fair sex are assigned a special examination-scoring. What this is, and what such procedures are needed for, we will consider in this article.

Why screening?

Screening is a special medicalexamination, which is prescribed for pregnant women and newborns to identify various pathologies and hereditary diseases. This study allows you to calculate the risk and establish the likelihood that the fetus may have any deviations in development. This is what screening is for. What is it really? For screening, a pregnant woman gives a blood test, and she has ultrasound (ultrasound). In addition, using these procedures, you can set the gender of the future baby.

Screening of newborns

If during pregnancy tests did not reveal possible abnormalities in the development of the fetus, then after the birth the child is also screened. What is it, and how is this procedure carried out?

second screening
All newborns are examinedchildren, it allows you to determine whether the child has genetic diseases. Usually, the procedure is carried out on the 3-4th day after the appearance of crumbs to light (in preterm infants on the seventh day). To do this, the heel of the newborn is taken from the blood and applied to a special sheet. On the form are printed circles, which must be filled with blood. Then the test-list is sent to the laboratory, where all the necessary studies are carried out, the results of which will be ready in ten days.

first screening
Prenatal Screening

This procedure is prescribed for pregnant women,It includes ultrasound of the fetus and a biochemical blood test. This examination reveals the risk of such deviations as Down's Syndromes, Patau, Edwards, Turner, Carnelia de Lange, Smith-Lemli-Opitz, triploidy and neural tube defects.

During pregnancy at different times (10-14weeks, 20-24 weeks, 30-32 weeks) are ultrasonically screened. What is it, knows, probably, everyone - this is the usual ultrasound. Also, at certain pregnancy terms, biochemical screening is prescribed. For this study, a blood sample is taken from a pregnant woman.

What else should I know?

The first screening is carried out for a period of 10-13 weeks. The results of this procedure are also taken into account in the second trimester. The second screening is done at the time of 16-18 weeks. This procedure allows you to establish up to 90% of cases of possible deviations in the development of the neural tube. It should be noted that the results of these tests can be affected by the following factors:

  • biochemical screening
    ECO;
  • bad habits, especially with regard to smoking;
  • disease in the future mother at the time of the test;
  • multiple pregnancies;
  • the weight of a woman plays an important role. With a significant body weight in the mother, the test scores can be overestimated.

I must say that the greatest advantagescreening is that at an early stage there is already an opportunity to follow the development of the future baby, and the mother, based on the received data, can make a deliberate decision: to interrupt or maintain her pregnancy.
