Prenatal Genetic Testing
To what extent should parents have access to prenatal genetic testing?
The debate about access for parents to prenatal genetic testing
starts its roots in the debate about religion vs. state. Should personal
choices like this be controlled by the state? What are they worried
about, abortion rates? Prenatal genetic testing does not automatically
mean more abortions, but maybe more prepared families. Another debate on
the topic is who should this be available to? Should it be for everyone
or only those mothers who are deemed “at risk”?
There are many reasons why a woman would want pre-natal genetic testing. She, herself, may have a condition that could possibly make her unborn baby a more at risk. The most common prenatal genetic tests are actually blood tests done on the mother. An example of a disease that would push for the mother’s testing would be like diabetes. The effect of diabetes would not cause the child to have diabetes but if the diabetes is not monitored properly by the mother then there could be a risk of low blood sugar for the fetus. In this case the testing would initially be done on the mother for the presence of diabetes and then further tests would go from there.
There are a few other things that the mother can be tested for before doing any tests on the actual fetus. The point of these tests is to rule certain diagnoses out and give the doctors a more narrowed scope of what they might be looking for in the fetus. Other than testing the mother for conditions like diabetes the mother’s blood type would be tested. The doctors look for the presence of Rh-negative in the mother’s blood, and if it is present there could be a risk to the child or future children if the fetus is Rh-positive. The risk with this is that the mother can actually produce antibodies against the unborn child’s blood. It is not usually harmful to the first child but the antibodies can build up and may even lead to death of future fetuses.
Another thing that the doctors will look for in the mother is presence of sexually transmitted diseases (STDs). There are approximately 2 million pregnant mothers each year in America with STDs (Cornforth 2004). A few of the diseases can affect the fetus through the placenta such as HIV and syphilis, while others may infect the child during a vaginal birth, such as gonorrhea, Chlamydia, hepatitis B, and genital herpes. These STDs can cause many problems and complications to the child including but not limited to cancer and death. It is very important to be aware of the STDs because some are actually treatable while the fetus is within the mother.
Another form of testing is by the use of an ultrasound. The good thing about using an ultrasound is that it is completely safe for both mother and baby. Ultrasounds also come into good use in determining age, sex, and growth of the fetus and can be done at anytime during the pregnancy. In its use to help determine the presense and extent of birth defects it can show proper connection of placenta and amount of amniotic fluid around the baby. Something to know about ultrasounds is that they might not be covered by medical insurance unless it is requested by a doctor for medical reasons. This shows how access to prenatal testing is not fully available for every woman.
Some tests can be done using amniocentesis or chorionic villus sampling which are more invasive but can actually give a definitive answer about the child’s health. These tests are mostly done only on mothers that show a ‘high risk”. High risk mothers include older mothers because these mothers have an increased chance to pass on chromosomal disorders. Chromosomal disorders are disorders where the child has a random error in their chromosomes, an example is Down Syndrome.
Although there are many reasons why mothers should get some tests done the decision is up to the parents, none of these tests are mandatory. The main reason to perform the tests would be to prepare the parents. Knowing certain information about the baby before it is born would be very helpful to planning for its arrival. It would give the parents time to get ready for the baby’s arrival by setting up special needs that the baby might have to have because of its condition. Knowing beforehand could also give the parents time to deal with their own emotions before having to deal with the actual facts.
The part that causes the most controversy is the fact that at the point of the genetic testing it is not too late to abort the fetus. Religious groups are against this because they see it as killing a human being, but is it truly cruel? Some parents might not have the resources to provide for a disabled child and take care of them like they deserve so instead of making them suffer, both the child and the parents, they make a tough decision. This paper is not to promote abortion but instead to show that not all abortions are really cold blooded murder and that it actually might be the best answer for the situation.The availability to these tests, like most things, is not universal for all women. The access to these resources are limited to the lower classes and some racial/ethnic groups. A big deciding factor, like stated above, is insurance. Not only the lack of amount of testing insurance will pay for, but the amount of pregnant women who actually lack medical insurance all together. Even women using Medicaid run into problems just trying to find an obstetrician that will accept their insurance. There are some government run programs to try to fix this problem but even then their access is limited. In conclusion, until everyone can agree on the need of access to these tests by all women things will stay as they are. The main focuses of the tests should be broadcasted to everyone. There are people who think that the tests are just to determine if the fetus has a disorder and then to terminate the pregnancy, but as described above the bigger reason for the testing is to prepare the families and/or alleviate any questions the parents might have. Like many things in society it is most important to get the correct information out there and inform the people.
