Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening. Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis.

This means that combined first trimester screening simply tells us if your risk is low or high.

Clinical Background [ return to contents ] Prenatal screening and diagnosis are routinely offered for detection of neural tube defects NTDs , Down syndrome, and trisomy Since the introduction of cell-free DNA testing, screening for trisomy 13 has also been offered. The intent of such screening and diagnosis is to enable pregnant women to make informed decisions regarding their pregnancies and be better prepared in the event of the birth of an affected infant.

The Disorders Neural Tube Defects NTD Neural tube defects NTDs anencephaly, open spina bifida or meningomyelocele, and encephalocele are a heterogeneous group of congenital malformations resulting from a failure of fusion of the neural tube. Anencephaly is almost always fatal at or within a few hours of birth.

The extra chromosome causes physical differences, developmental delays and a tendency toward certain health problems. This condition is incurable, but testing during pregnancy gives parents the chance to prepare for the unique needs of a child with birth defects, as well as identifying any specific abnormalities that may require medical care after birth.

In fetuses with chromosomal abnormalities, cardiac defects and many genetic syndromes the NT thickness is increased.

Nuchal translucency scans (ultrasound) are normally done between 14 weeks of pregnancy. They measure a small fluid collection within the skin at the back of the baby’s neck (nuchal translucency) to help identify the risk of Down’s syndrome and other chromosomal abnormalities.

Grant, MSN, RN Abstract This article presents a discussion of screening principles and techniques available to screen for common birth defects during pregnancy. The most common birth defects identified by screening include neural tube defects and chromosome abnormalities. Nurses employed in prenatal care settings need to have accurate information they can provide to women so they understand the benefits and limitations of screening. Timely presentation of information and identification of available resources will help nurses minimize confusion and provide support for women as they proceed with pregnancy screening.

September 30, “Prenatal Genetic Screening. Screening, AFP, Down syndrome, neural tube defect, false positive Introduction Modern childbearing has brought with it new and expanding reproductive testing options that provide women with previously unavailable information about their pregnancies. Screening Screening in both clinical and community contexts is promoted as a cost-effective means of identifying individuals who have an increased risk for disease and is an important component of public health efforts Croyle, There is, however, considerable confusion and misunderstanding that surrounds screening techniques.

A A screening test does not give a yes or no answer but identifies increased risk for certain disorders so that definitive diagnostic tests can be offered. Screening is targeted at apparently healthy individuals who are not aware of symptoms. Screening limits the number of people who have to undergo diagnostic tests that may be expensive or have an element of risk associated with them.

Most individuals called positive by screening are false positive.

Our sonographers are all accredited by the fetal Medicine Foundation also. Ultrasound scan screening is for Down’s syndrome as well as Edward’s syndrome and Patau’s syndrome and Turner’s syndrome. The ultrasound scan measures the nuchal translucency thickness and the presence or absence of the nasal bone of the baby as the majorities of babies with Down’s syndrome may have an increase in the fluid collection behind the baby’s neck and may also have absent fetal nasal bone.

Nuchal translucency measurements as well as the blood test in the first trimester of pregnancy The Combined Test may avoid the needs for amniocentesis.

Introduction Over the last 20 years, new technology has improved the methods of detection of fetal abnormalities, including Down syndrome. While there are ways to diagnose Down syndrome by obtaining fetal tissue samples by amniocentesis or chorionic villus sampling, it would not be appropriate to examine every pregnancy this way. Besides greatly increasing the cost of medical care, these methods do carry a slight amount of risk to the fetus.

So screening tests have been developed to try to identify those pregnancies at “high risk. What is the difference between a screening test and a diagnostic test? In diagnostic tests, a positive result very likely means the patient has the disease or condition of concern. In screening tests, the goal is to estimate the risk of the patient having the disease or condition.
