Abortion After Prenatal Testing
Methods of Prenatal Diagnosis
There are four methods of prenatal diagnosis that is available to women. The first and most commonly known is ultrasonography, colloquially referred to as "ultrasound." A picture of the fetus is developed through the implementation of sound waves. Ultrasound is used to identify abnormalities that are physically apparent such as deformed limbs, defective chest, and heart. During the fourteenth to sixteenth week of the pregnancy, neural tube defects can also be detected (Cassidy & Gentles, 2002). There are other uses such as detecting multiple fetuses and measuring fetal growth.
The second method is Maternal Serum Alpha Fetoprotein Screening (MSAFP). Its primary purpose is to detect neural tube defects by measuring the alpha fetoprotein levels in the women's blood. High levels of alpha fetoprotein can indicate neural tube defects in the fetus. This exam is typically administered during the fifteenth to seventeenth week of gestation (Cassidy & Gentles, 2002).
Amniocentesis, the third method, is an invasive procedure as it requires inserting a needle through the mother's abdominal wall and into the amniotic sac. Once in the amniotic sac, fluid is withdrawn. The amniotic fluid is tested for chromosomal abnormalities such as Down syndrome, Edwards syndrome, and Turner syndrome (Yashon & Cummings, 2012). There is a risk of miscarriage associated with amniocentesis, however...
