The Pros and Cons of Prenatal Screening

Children are gifts from God. Every parent wants to have a healthy child. Anomalous growth of the fetus is now commonplace. These abnormalities may be due to physical, radiation and chemical factors. The most common factors are genetic mutation, accumulation of abnormal bodies, mental retardation caused by other conditions, causing many problems to the children themselves and their parents. Modern technology and innovation in the medical field has developed a method called prenatal screening to detect abnormalities before birth and to prevent this future tragedy.

Prenatal diagnosis or prenatal screening (note that "prenatal diagnosis" and "prenatal screening" refers to two different types of tests) is an examination of prenatal fetus or embryonic disease or condition. Through a series of periodic inspections, obstetricians and midwives can monitor the health and prenatal development of pregnant mothers. In some countries such as the UK, Joint Health Found Height (SFH) is measured as part of a prenatal reservation for 25 weeks pregnancy. (SFH measures from the woman 's pubic bone to the upper part of the uterus). There is insufficient evidence to indicate whether measuring SFH is useful for detecting small or large babies as the review of this approach has only found a study. Because SFH measurement is not expensive and it is used in many places, we recommend continuing this method in review.

A rich prenatal screening test menu for pregnant women is now available. Most screening tests include blood tests and ultrasound examinations (sound map). Blood tests (or serology screening tests) measure the amount of various substances in the mother's blood. Along with the age of females, these are used to estimate the possibility that her child has down syndrome. These blood tests are usually done in conjunction with detailed ultrasound examinations to examine "markers" (features that some researchers believe are significantly related to Down's syndrome). A new advanced prenatal screening can now detect chromosomal material circulating in the mother's blood. These tests are not invasive (as in the diagnostic tests below), but provide high accuracy. Nonetheless, not all of these screenings clearly diagnose Down's syndrome. Women of all ages are currently undergoing periodic prenatal screening and diagnostic testing.
