	Prenatal diagnosis - Wikipedia, the free encyclopedia
		Prenatal diagnosis is the diagnosis of disease or condition in a fetus or embryo before it is born.
		If abortion isn't an option for a particular couple (because of their own beliefs), invasive prenatal diagnosis of such a condition is unhelpful as the test puts the child at risk, and knowing the result doesn't help the child.
		Diagnostic tests, such as amniocentesis, are considered to be very accurate for the defects they check for.

	Aspergian Pride - Autism Prenatal Testing
		Prenatal testing research is part of today's widespread climate of intolerance toward the autistic population, manifested not only in eugenics funding, but also in "cure" campaigns that use military rhetoric.
		For example, there is a prenatal test for neural tube defects, which makes it possible to cure or greatly reduce spina bifida by performing surgery on a fetus while it is still in the womb.
		When prenatal testing is used for purposes of abortion, it reflects a social value judgment on whether or not a particular group of people has any intrinsic worth as human beings, on who should and who should not inhabit the world.

	The DNA Files - PRENATAL GENETIC TESTING - The Topic In-Depth
		While the ethical debate over prenatal testing has persisted since The DNA Files's original coverage of this issue in 1998, new technologies and approaches to detect, prevent or avoid disease in babies continue to be developed.
		Carrier screening, in which populations of couples are tested for their risk of having a child with a particular genetic condition, has allowed prospective parents to assess their risk of having children with diseases such as Tay-Sachs disease and sickle-cell anemia for over 20 years.
		Testing is usually offered only to pregnant women considered to be at higher-than-average risk due to age, family history, or ethnic or racial background associated with higher incidence of a particular disease.

		Early prenatal care is therefore a crucial part of preparing for the birth of a child.
		Prenatal diagnosis of birth defects that require intensive acute care at delivery allows planning of the delivery at a center where experts are present who can deliver the specialized medical and skilled nursing care these infants and their families need during the neonatal period.
		For other families, the prenatal diagnosis of a condition so serious that their infants will likely not survive delivery allows them time for emotional preparation and an option to choose delivery in their local area with the support of friends and family in a familiar setting.

	Prenatal Tests
		Prenatal testing is further complicated by the fact that approximately 250 birth defects can be diagnosed in a fetus - many more than can be treated or cured.
		If the fetus doesn't move during the test, he or she may be asleep and the health care provider may use a buzzer to wake the baby.
		This test stimulates the uterus with pitocin, a synthetic form of oxytocin (a hormone secreted during childbirth), to determine the effect of contractions on fetal heart rate.

	Prenatal Genetic Testing
		In an article discussing perceptions of predictive testing for Huntington’s by young women, prenatal testing for late onset diseases was considered acceptable by half of the women; only one quarter of the total group would terminate a pregnancy of a child that might develop a late onset disease.
		Prenatal "exclusion testing"-a test to exclude the risk of a condition in a foetus- is used with Huntington’s.
		The pregnancy is therefore tested with linked markers and not mutation analysis to determine if the parent at risk has passed on the chromosome region in question of the affected or unaffected grandparent; the pregnancy is now at a 50% or 0% risk.

		AFP Screening: This test (the alpha-fetoprotein test) is a screening to determine the possibility of spina bifida or Down’s Syndrome in the fetus.
		This test is generally recommended to mothers over the age of 35 but can be refused if the parents do not feel that it is necessary.
		If the test is positive, the mother will generally be put on antibiotics during labor to prevent the baby from contracting it during birth.

	Prenatal Testing
		Additional tests may be recommended by your caregiver for identification of genetic disorders or to check the well-being of your baby.
		This test involves the removal of a small sample of tissue by a catheter inserted through the vagina and cervix, or through a needle inserted into the abdomen and placenta.
		To perform this test, the mother is either given a drug called oxytocin to make her uterus contract, or she is told to rub one of her nipples lightly, which causes her body to release oxytocin naturally.

		Blood tests and imaging studies to screen for common conditions are routine in most pregnancies.
		If a screening test indicates a possible problem — or your age or family history puts you at increased risk of having a baby with a genetic problem — you may consider more invasive diagnostic testing.
		But if prenatal testing indicates that your baby may have a birth defect, you may be faced with wrenching decisions — such as whether to continue the pregnancy.

	Prenatal Testing for Down Syndrome
		In screening tests, the goal is to estimate the risk of the patient having the disease or condition.
		However, screening tests have more chances of being wrong: there are "false-positives" (test states the patient has the condition when the patient really doesn't) and "false-negatives" (patient has the condition but the test states he/she doesn't).
		Once the blood test results are determined, a risk factor is calculated based on the "normal" blood tests for the testing laboratory.

		This test is normally taken between the 15th and 20th week of pregnancy and looks for three elements in a pregnant woman’s blood: maternal serum alph-fetoprotein (MSAFP), the human choronic gonadotropin (HGC), and estriol.
		Prenatal testing can provide reassurance of fetal health for the mother and her physician.
		It should be noted that not all women need prenatal tests during their pregnancies to have a healthy baby.

	Common Prenatal Genetic Testing
		Prenatal genetic testing generally refers to tests that are done during pregnancy to either screen for or diagnose a birth defect.
		The main goal of prenatal genetic testing is to provide families with information to make informed choices about pregnancy and reproduction, and to assist the woman's physician in providing the best care and management for her pregnancy.
		The test identifies those women who are more likely to have a baby with an open neural tube defect, Down syndrome, or trisomy 18.

	Prenatal Tests
		Parents who refuse a test or procedure without justification, or who refuse testing in medically indicated situations, are doing themselves a disservice, as well as disrespecting their caregiver.
		There is a domino effect here, as many prenatal tests have high false-positive rates (meaning there isn't anything wrong, but the test says there is) or are just plain not accurate in either direction (meaning they may not detect the problem they are testing for a large portion of the time either).
		Doctors order all this testing because they are the most sued people on the planet and they are covering their butts with all these tests.

	Prenatal Testing
		Many years' experience has shown conventional karyotyping of cultured amniocytes to be a reliable, cost effective and highly accurate means of prenatal diagnosis of a wide range of chromosome abnormalities, its only disadvantage being the period during which cells need to be cultured prior to analysis.
		Several commercial kits are now available, but presently all have the disadvantage that inherent technical limitations, combined with the need to contain their price within acceptable limits, restrict their scope to the accurate detection of non-mosaic forms of the common aneuploidies, trisomies 13, 18 and 21 and numerical sex chromosome abnormalities.
		Although rapid testing for common aneuploidies clearly offers advantages to some groups of patients, its widespread applicability and its desirability as a screening technique for use for all current prenatal diagnostic referrals, remains under review.

		When and whether prenatal testing is okay depends on two things: (1) the good to be achieved by doing the test and (2) the danger the test itself poses to the child.
		Some tests seem to pose little risk to the child and can be done as long as one isn't tempted to do something immoral (like have an abortion) if one finds out that there is a problem with the child.
		If prenatal diagnosis respects the life and integrity of the embryo and the human fetus and is directed toward its safeguarding or healing as an individual, then the answer is affirmative” (sec.

	Prenatal Paternity Testing
		Similar to a standard paternity test, a prenatal paternity test compares the baby’s DNA profile with that of the alleged father and the mother.
		Unlike a standard paternity test, the mother is usually required to provide DNA samples for analysis, in addition to participating in the procedure for sampling of the baby’s DNA.
		These tests are never usually advised for just paternity reasons; most often, the mother needs the tests for other health issues.

		Recently, the California Birth Defects Monitoring Program stated, "One in every 33 babies is born with birth defects-- the leading cause of infant death and childhood disability." There are many questions patients often ask when considering the health of their unborn baby.
		Each women seeking information regarding prenatal diagnosis should be aware of (1) which tests are available, (2) what each test attempts to accomplish, and (3) the questions she should ask physicians offering these studies.
		One final point to consider is that the prenatal detection of birth defects and other fetal problems is dependent upon the skill and expertise of the physician performing and/or interpreting the ultrasound examination.
