Prenatal Testing & Babies with Disabilities

A Compassionate Approach

Prenatal tests – are they a useful tool to help parents and babies? Or, are they a means to search for and destroy babies with disabilities in the womb?

The answer is yes to both. Unfortunately, the “search and destroy” use is most prevalent today, and challenges you to think about the meaning and worth of people with disabilities. If parents want a baby, but not a baby who isn’t “perfect,” the result is clearly discrimination.

Western culture is driven towards the ideal – towards perfection. We live in a society that worships physical beauty, applauds academic and economic achievement, and strives to attain the “good life.”

Often, people in pursuit of perfection recoil at the sight of physical disfigurement. They sometimes voice outrage at allowing the birth of “defectives,” questioning their ability to contribute to society in any meaningful way. Yet, a person with a disability is a human being with gifts, abilities, potential, and feelings.

Most babies diagnosed with disabilities before birth are being aborted instead of given a chance at life. Societal pressure to destroy such an imperfect life is enormous. Yet, babies with disabilities need to enjoy the same privileged right to life that you do.

Pressure to Abort a Special Needs Baby

Doctors feel obligated to offer prenatal tests out of fear they will be successfully sued for the “wrongful” birth of a child with a disability. If you have had a prenatal test and been told that your baby has special needs, you may feel pressure from medical staff and/or family members to end the child’s life through abortion.

You are probably emotionally upset and frightened for your future and that of your child. It is important to focus on the fact that this is your child, perfect or not. There are numbers of support systems available for your family both before and after birth. There are people willing to adopt your child if you feel unable to take care of him.

Remember that prenatal tests are not always accurate, and your baby’s prognosis as explained by the medical team may be overly grim. As hard as it seems, staying positive and optimistic will assist you greatly.

If your medical team does not support your having your baby, you may have to seek a new team. Be prepared to respond positively to negative attitudes towards your child. You could say to family or friends: 

“The doctors have told us that our baby may have some problems but we’re going to wait and see. We won’t know for sure until the baby is born.”

Prenatal Tests

The following tests can be conducted during pregnancy:

Amniocentesis

Most common prenatal test which is done around 15 to 20 weeks 1 into the pregnancy. A sample of amniotic fluid is extracted from the mother’s womb and the fetal cells are tested for abnormalities. A 0.5 % miscarriage rate is associated with amniocentesis.2

Chorionic Villus Sampling (CVS)

Conducted early in pregnancy, usually from 10 to 13 weeks. Some of the chorionic villi cells are taken from the placenta at the point where it attaches to the uterine wall, 3 and fetal cells are tested for abnormalities. There is no consensus of what the miscarriage rate from CVS is. Some reports show it to be the same as that for amniocentesis and some to be twice that of amniocentesis. “There appears to be an even higher risk of miscarriage with the transcervical CVS technique compared to the transabdominal technique. Other factors that further increase the risk of CVS include having the procedure three or more times and having a fetus that is smaller than normal for their age. The physician’s skill and experience also play an important role.” 4 CVS is also associated with the birth of babies with limb abnormalities, especially when CVS is performed before the 10th week of pregnancy.5

Alpha-fetoprotein Test (AFP)

Conducted between 15 to 20 weeks into pregnancy.6 Blood sample is taken from the mother. This test is unreliable and associated with high false negative results, meaning that an abnormality is detected when none exists.

Ultrasonography

Conducted at any time during pregnancy. An ultrasound picture assists in detecting visible abnormalities of organs and limbs.

Combination of Tests

Conducted to verify or substantiate results of other tests.

More prenatal technologies become available each year to test for certain diseases that an unborn child might have.

Conditions Detected in Utero

It is now possible to diagnose approximately 450 conditions in utero by testing fetal cells. This number could skyrocket to almost 6,000 conditions in the future. 7

The most common victim of abortion following prenatal testing is the child with Down syndrome which affects one in 800 to 1,000 births.8Down syndrome is most often associated with women who become pregnant at an older age. For women in the 20-24 age group the occurrence of Down syndrome is one in 1,490 births, for women over 40 it is one in 60, and for age 49, it is one in 11 births.9

Although probability increases with maternal age, 80% of children with Down syndrome are born to women under the age of 35, reflecting the overall fertility of that age group. 10

Although not considered a severe disability, 81 – 91% of Down syndrome children detected prenatally have their lives ended by abortion. 11,12,13,14

The second most common abnormality is the presence of a neural tube defect (NTD) which is “any defect of the brain and spinal cord caused by failure of the neural tube to close during growth during pregnancy….” The incidence of NTD is the highest in Appalachia with one case in 1,000 births. Worldwide, the incidence of NTDs is 0.6 – 1.3 cases of 1,000 births.15Approximately 2,500 infants with NTDs are born in the United States each year.

Neural tube defects cause conditions known as spina bifida (open spine), anencephaly (lack of brain formation), and encephalocele (an abnormal closure of the spinal column). Anencephaly is a condition incompatible with life, and these infants usually die within a few hours or days.

Typically, spina bifida – the most common disabling birth defect 16 – is accompanied by hydrocephalus (fluid on the brain) in 70% to 90% of infants.17 Intellect of children with spina bifida can range from profound retardation to high intelligence, although few have profound retardation.

Around 1993, an exciting medical finding concluded that folic acid, a simple, widely available water-soluble vitamin, can prevent spina bifida and anencephaly. The U.S. Public Health Service recommends that all women who could possibly become pregnant get 400 micrograms (or 0.4 mg) of folic acid every day. This could prevent up to 70% of some types of serious birth defects. But to do this, women need to take folic acid before they get pregnant. 18

Prenatal tests also indicate the sex of a child. Although not reported in significant numbers, a certain number of women abort a child of the undesired sex. In India, there are reports of numbers of girl babies aborted because they are the wrong sex.

The overall rate of abortion when an abnormality is detected in the child is at least 73%, with some authorities placing the rate between 80% and 100%. 19

Tests are routinely conducted on living human embryos conceived through in vitro fertilization. Embryos with genetic defects are destroyed or not implanted in the mother.

In Utero Treatments

There is a bright side to prenatal testing with the advent of in utero treatments for unborn babies. The baby is rightly treated as a second patient. Microsurgery on the spine of a baby with spina bifida can be conducted in utero to correct a defect or limit the impact of the defect.

In 1999, Samuel Armas jolted the surgeon performing surgery on him in utero when little Samuel reached out of the womb and grabbed the surgeon’s finger.

In addition to in utero surgery for spina bifida, surgery can also be done for heart defects, facial defects, and Amniotic Band Syndrome (a set of congenital birth defects believed to be caused by entrapment of fetal parts [usually a limb or digits] in fibrous amniotic bands in utero.]

Should You Have a Prenatal Test

Because of fear of a “wrongful” birth lawsuit, your doctor is most likely to recommend prenatal tests at some time during your pregnancy. Ultrasound testing is done routinely during pregnancy to assist your doctor in caring for you and your child.

So, the question arises – should you have a prenatal test? And what will you do with the information? Unfortunately, in utero treatments are not available for most detected problems. If you have no desire to abort your baby, you should decline tests for the following reasons:

  • Some tests have the complication of miscarriage, even if there is nothing wrong with the baby.
  • The diagnosis may be wrong.
  • The abnormality may not be as severe as the diagnosis suggests.
  • Even if a child is afflicted with a condition that limits his life or potential, the child has the right to his own life.

And, aborting a child, even one with health problems, may cause significant psychological problems for the mother.

Where to Find Help

Unquestionably, society must be concerned about the additional stress placed on a family caring for a child with a disability. We must be committed to providing services which not only assist the family but also offer opportunities for the child to reach her full potential. Fortunately, many of these programs now exist.

  • Educational programs geared to the needs of individuals with disabilities.
  • Birth-to-Three intervention programs whose goal is to enhance the development of the child in the earliest years when results are most beneficial.
  • Vocational and transition programs to train those with disabilities.
  • Assistive technology which perfects technological devices, such as computers and voice boxes, to assist specific disabilities.
  • Independent living programs to allow persons with disabilities to live in the community.
  • Codes requiring public places to provide access for people in wheelchairs. 
  • Special needs adoption programs.

Ethical Questions

Not only are there ethical questions about killing unborn children, but the technology of prenatal testing raises additional questions regarding whether or not having a baby is analogous to buying a car. There is widespread support for supporting abortion if a serious genetic defect is identified during pregnancy. “70 percent of Americans said they believe that women should be able to obtain a legal abortion if there is a strong chance of a serious defect in the baby according to a 2006 poll conducted by the National Opinion Research Center.” 20 This raises the specter of a eugenics society which regards the perfection of the person as more important than the existence of the person.
