	Fetal screening - Wikipedia, the free encyclopedia
		Fetal screening refers to any tests that allow a fetus to be tested for certain traits or characteristics.
		Most often this is performed to test for birth defects.
		In some cases, fetal screening has been done to determine characteristics generally not considered birth defects.

	OBGYN.net - The Female Patient: Ultrasonographic Screening for Fetal Malformations
		The frequency of fetal malformations and the undesirable consequences for affected infants and their families are convincing arguments for using this modality on a routine basis.
		Screening a specific population sample is justified when the anomaly is present in a significant number of cases and is deleterious; appropriate interventions can be carried out in a timely fashion; and the screening procedure itself is safe, reliable, easily available, and cost-effective.

		The former identifies an increased likelihood of a fetal abnormality in an apparently normal pregnancy, whereas the latter confirms or refutes the existence of an actual anomaly in a fetus believed to be at increased risk [1].
		Fetal nucleated cells such as trophoblasts, erythrocytes and white blood cells are found in maternal blood, and have been widely pursued as potential substrates for noninvasive prenatal diagnosis.
		Using fetal DNA in maternal plasma for the screening of fetal chromosome aneuploidies is possible, especially in conjugation with other established serum markers [101].

	Paper session 1: Ethical dilemmas & fetal screening - NNDR, 6th conference, Iceland 2002 (Site not responding. Last check: 2007-10-19)
		When prospective parents must cope with the often difficult results that follow fetal screening and/or diagnosis, they take for certain that the choices or solutions offered to them by health professionals are compatible with the professional and ethical values that the public health services are based on.
		This paper analyses ethical aspects of screening in general and in particular prenatal screening for Down syndrome (DS) and other fetal abnormalities by ultrasound in early pregnancy (week 11-14), as Icelandic authorities currently consider to offer such screening tests to all pregnant women - regardless of their age and risk status.
		This cannot be achieved without inflicting harm to others, since the screening programme will necessarily imply loss of approximately one healthy fetus for every two births of a fetus with DS that can be prevented, due to the risks associated with invasive diagnostic testing.

		Screening for FAS in children of school age would be a useful target population.
		Community-based screening of this group and high risk populations should be considered as an option to increase the completeness of ascertainment and to develop prevalence estimates.

	Guide to Clinical Preventive Services Assessment
		Screening tests are evaluated in terms of their effectiveness when performed during the clinical encounter (i.e., case-finding).
		Screening tests are those preventive services in which a special test or standardized examination procedure is used to identify patients requiring special intervention.
		This refers to the tendency of screening to detect a disproportionate number of cases of slowly progressive disease and to miss aggressive cases that, by virtue of rapid progression, are present in the population only briefly.

	Fetal Ultrasound Screening
		Examples of screening tests would be the PAP smear for cervical cancer, mammography for breast cancer, and the Maternal Serum Alpha-Fetoprotein Test to identify fetuses at increased risk for spina bifida or Down syndrome.
		A large screen television monitor is mounted on the wall so that the patient and her family or friends can view the ultrasound examination as it is being performed.
		The technique which I employ to examine fetal anatomy is derived from a similar approach used in computerized tomography in which the body is examined in transverse and longitudinal planes.

	Chapter 6 Screening for Fetal Abnormalities
		If there are any openings in the fetal skin, an unusually large amount of alphafetoprotein escapes into the amniotic fluid and crosses the placenta to the mother's blood stream.
		The AFP assay measures the concentration of certain hormones in the mother's blood to predict whether the fetus is likely to have a neural tube defect or a chromosomal abnormality.
		It is important to remember that the AFP assay is a screening test, not a diagnosis.

	Todros T, Capuzzo E, Gaglioti P. Prenatal diagnosis of congenital anomalies. Images Paediatr
		In the late 1990’s, ultrasound screening at 10-14 weeks has increasingly included measurement of nuchal translucency, which is the maximum thickness of the subcutaneous translucency between the skin and the soft tissue overlying the cervical spine of the fetus.
		From published series of structural cardiac anomalies detected during fetal life it is apparent that the closest figure to the true incidence of CHD in the general population of fetuses is 1 percent.
		Fetal echocardiography should be performed in groups selected on the basis of patient history and sonographic anomalies or markers, including extracardiac anomalies, maternal diabetes, infection, suspicious scan on screening, chromosomal aberrations.

	How to perform basic antenatal screening with fetal echocardiography - Contemporary OB/GYN
		By Richard M. Benoit, MD, and Joshua A. Copel, MD The goal of routine screening of the fetal heart is establishing that cardiac structure and function meet certain criteria (Figure 1).
		The cardiac axis refers to the position of the fetal heart in the chest, and can be determined by measuring the angle formed between the interventricular septum and a line from the spine to the anterior chest wall that divides the fetal thorax in half.
		The fetal heart typically lies at a 45-degree angle from the midline, and 95% of normal hearts are between 30 and 60 degrees of axis.

	New Era Near For Fetal Screening? - CBS News
		They were able to correctly determine whether the gene mutation used for diagnosis of beta-thalassemia was present from the fetal DNA in 80 to 100 percent of the cases, with only one false-positive test.
		The researchers say the study proves that fetal genetic traits can be detected from the analysis of fetal DNA in the mother's blood, and add that the blood test is relatively simple and cost-effective.
		The new research adds to the evidence that there are plenty of fetal cells and fetal DNA in the mother's blood, and the ability to separate the fetal material opens up the door to a wide range of screening as our understanding of genetics progresses and more genetic causes of disease are discovered.

	BMA - Diagnosing fetal abnormality
		Some form of prenatal screening is offered routinely to every pregnant woman in the UK in order to identify those at high risk of having an affected child, so that prenatal testing for the disorder may be offered.
		Written information should be provided to all women giving details of the nature and purpose of the screening proposed, the procedure used, details of detection rates for defined common conditions, the meaning of a positive and negative screening result, and possible actions to be taken if a normal or abnormal result is obtained.
		In relation to screening for Down syndrome, the information obtained from these tests is combined with the woman’s age and gestation of the fetus and a computer algorithm calculates the likelihood of an affected pregnancy.

		9 The efficacy of screening with an AFP was comparable to that based on age alone, 20% to 25% detection rate with a 5% false positive rate.
		If the first trimester screening is positive, the couple have the option of no further diagnostic testing, diagnostic testing via chorionic villi sampling (CVS) or second trimester amniocentesis, and/or whether or not to continue the pregnancy (see Fig 1).

		Fetal death is often detected at this time where no fetal heartbeat is observed.
		The amniotic fluid is largely fetal urine, and if there is too small a volume of amniotic fluid (called oligohydramnios), the inference is that something has interfered with fetal urine output — for example, an obstruction at the bladder neck or at some other site from the kidneys on down.
		Fetal growth restriction observed as early as the second trimester, especially with associated oligohydramnios, suggests that a poor outcome to pregnancy is likely.

	Ultrasound Screening For Fetal Anomalies: Is It Worth It? A New York Academy Of Sciences Conference
		NEW YORK, JUNE 11, 1997 -- With the introduction of ultrasound screening in the 1970s, the uterus of a pregnant woman ceased to be "a closed space that effectively hid most of its secrets."* Today, ultrasound screenings during pregnancy often provide detailed information regarding a developing fetus.
		Ultrasound screening uses sound waves to produce an image of a fetus, which often helps clinicians in detecting fetal anomalies in utero, such as malformations and congenital heart abnormalities.
		Conference co-chairs are Frank A. Chervenak, professor of obstetrics and gynecology, Cornell University Medical College, and director of the departments of obstetrics and maternal-fetal medicine, The New York Hospital, and Salvator Levi, professor of Obstetrics and Gynecology, Universite Libre de Bruxelles, and head of the ultrasound department, Centre Universitaire Brugmann.

		There is no known incremental risk of adverse drug effects associated with delayed administration of additional RhIG, but the actual benefit has not been tested or proven in prospective clinical studies.
		When concern for Rh alloimmunization exists, patients can be screened subsequently for formation of anti-D antibodies (Type and Screen).
		This screening should be performed no earlier than 6 months after receiving a dose of RhIG, as the drug may cause the antibody screen to be positive and not accurately indicate the patient's immune status.
