Genetic testing is a type of medical test that identifies the changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a genetic condition and if it can be passed on. I feel that genetic testing’s pros outweigh the cons. The physical risks of the genetic testing are very small. A positive result of genetic testing can help a person maintain prevention, and treatment options. Some test results can also help people make decisions about having children. Newborn genetic screenings can help identify genetic disorders early in life so treatment can be started as early as possible so that the unwanted gene will not pass on.
Most of the opinions in the genetic testing seminar were on the positive side, choosing that it should be used more often. The generic testing can help better prepare people for what they can pass down if they choose to have children. For example, if someone has the high risk of diabetes running in their family their most likely to have it passed down to their children and even getting it themselves. I think the majority of people want to know what their genes carry, because it can have a huge impact on their life. Technological advances in genetic testing lend parents new insight about their children's risk factors for developing diseases later in life. The issue has been the subject of heated debate as parents grapple with the pros and cons of testing themselves and their children.
Genetic testing can help people determine why they get cancer or other diseases. Genetic testing is recommended to people who have a family history of a genetic disease, have children who are born with genetic defects, and have gone through more than one miscarriage in the past. Though these te...

... idea to take part in. Genetic testing can lead to a global preparation for parents to look out for their children. The genetic test results can determine so much for the children and what they might get passed down to them whether its diabetes, cancer, or any other illness or disease.
For example, if someone is of Jewish descent have a higher prevalence of harmful BRCA1 and BRCA2 mutations than people in the general population. Other ethnic and geographic populations around the world, such as the Norwegian, Dutch, and Icelandic peoples, also have higher prevalences of specific harmful BRCA1 and BRCA2 mutations.
In addition, limited data indicate that the prevalence of specific harmful BRCA1 and BRCA2 mutations may vary among individual racial and ethnic groups in the United States, including African Americans, Hispanics, Asian Americans, and non-Hispanic white.
Advantages of genetic testing may be helpful in determining whether or not you have a disease or are proba...
“The highest rated science program on TV called NOVA made a documentary surrounding genomic testing called, Cracking Your Genetic Code (NOVA, 2008).” This documentary demonstrated and described different techniques of what is genetic testing, how genetic testing is performed, and all the individuals whom benefit from these special DNA techniques. What is DNA? “DNA is material that governs inheritance of eye color, hair color and many other human and animal traits (Riley, 2005).” DNA is developed from the pairing of genes from a female and male gametes (Health & Prenancy, 2012). These gametes fuse together during mitosis and meiosis, getting 23 chromosomes from each parent, in order, to develop an embryo. In this embryo is DNA. DNA is made of 4 different amino acids, in which, are the building blocks for DNA and they are A, T, G, & C. These building blocks have base pairing in a series of sequences and this sequence is what makes up genes. Genes are codes that can read in this sequence to determine what kind of traits offspring is going to have. Through genes DNA testing can be perform to find mistakes. In this documentary, many different genetic testing were performed and some may agree that this can be very controversy because some people will rather not know certain things unless there are signs or symptoms. However, others find this DNA testing as an advantage and knowing this information can prepare them for the “what if” factor. In my research, I will be discussing what genetic testing is, what it provides, what the benefits are, the risks, and what companies provide genomic testing.
In Gattaca, the plot focuses on the ethics, the risks, and the emotional impact of genetic testing in the nearby future. The film was released in the 90s; yet in the present, the film does not give the impression of science fiction. Today, genetic testing is prevalent in many aspects of the scientific community. This paper will describe genetic testing, its purpose, diagnostic techniques that use genetic testing, relating Huntington’s disease to genetic testing, and the pros and cons of genetic testing.
Genetic Screening comes with a lot of pros and cons. It's great for people who come from families with a common disease because there is a chance that genetic screening will inform them whether or not they have that disease. Unfortunately, the outcome is not 100% accurate. Therefore, the results aren't always necessarily true. Those who choose to go under the screening and receive great results are very lucky because they were saved from going through the difficult process of taming a disease. Those who go under the testing and do not receive good
Gene testing is the practice of testing individuals who show no symptoms to determine whether they carry genes that could cause them or their children to develop certain genetic diseases later in life. Gene screening is a very controversial topic because of the risks that come with it. Would you want to know if you’ll develop a life threatening disease later in life? Many individuals would want to know this, but some would not. Personally, I think gene testing is ethical under certain conditions.
There are several types of genetic tests that can give us a broad amount of information about ourselves, our parents and/or children (What is testing?). Personally, I see advantages and disadvantages to it. Anyone is able to find the probability of them having a disorder or disease and start dealing with before it gets to a lethal stage. For women, it is reassuring to know whether a disorder that they possess can be passed on to their children or not. They can also know whether their child is healthy or not before it is even born. It also impacts on how scientists deal with diseases since they are given a different output of the disease at its early stages and allows them to study it until a cure is found. But what happens when your private information goes public? People will be treated differently because of a high risk of having a cancer in the future. In your CV, your past experiences and your qualities will be accompanied by your genetics test results that inform the company whether you will be a risk to them in the future. A new kind of discrimination will be created in our society. A second major disadvantage to genetic testing is people using it for “superficial” purposes like changing children’s eye colors and other biological characteristics that should not be changes. Above the disadvantages are the benefits which are why I am all for the genetic testing for health-related purposes.
Genetic testing involves examining an individual’s DNA and identifying abnormalities within the chemical makeup of specific structures. It, essentially, maps the person’s genome and can be interpreted to predict future issues. By analyzing the chromosome, genes, and even certain proteins, physicians and researchers can find changes that lead to inheritable disorders. These changes can lead to possible diagnosis or cure for the disorder in question. In most cases, genetic testing is used to determine the probability that an individual will develop a certain disorder. It is not used to specifically diagnose a disorder, as there are no techniques that are 100% accurate. Genetic testing techniques do give good evidence to confirm a physician’s findings, but it is not the first act a physician takes to diagnose a disorder. It can narrow a search or rule out a specific disorder very confidently, but making a diagnosis based solely on genetic testing is not an action that a qualified medical professional would consider.
It is patients’ right to opt for genetic testing on their own DNA, although they are accepting a great risk by doing so. DNA is unique to each individual, present in each individual since conception, and influences who each individual is, so the information contained within it belongs to each patient, despite the risks. Such risks include DNA testing services providing results to potential employers or insurers, who can make decisions at the disadvantage of the patients if high disease probabilities are discovered. The results can also cause patients to react emotionally poorly and make negative changes to their lifestyles. Although risky, patients deserve the rights to take these risks if they choose to do so.
Genetic screening can be used to refer to any activity that locates or advises people about genetically connected diseases. The first large-scale genetic screening project began in the 1960's with the Guthrie test which tests infants for PKU (phenylketonuria) (Munson, 1996). Currently with the advances being made by the Human Genome project we are achieving a much more detailed understanding of the relationship between specific genes and diseases. Approximately nine hundred gene or gene markers have been linked to diseases (Munson, 1996). With all of the new information about our genes, the ability to develop tests to screen for these genes is becoming possible for a much larger number of diseases. Some of the current DNA tests available diagnose Adult polycystic kidney disease, Alpha-1-Antitrypsin deficiency, familial adenomatous polyposis, hemophilia, Huntington's disease, myotonic dystrophy, and familial breast cancer susceptibility (Munson, 1996). Many more tests are well on the way to being developed. With the possibility o...
One of these issues is the moral and ethical issue of genetic testing. Genetic testing is a controversial topic that affects patients, fetus to adult. For the sake of keeping this article from being too broad, I will focus on prenatal and fetal genetic testing. Proponents of genetic testing argue that it is a form of preventative medicine, allowing the parents to be prepared or make decisions about a child before the child is born. They may point out that with knowledge of defects or disabilities while child is in utero, medical staff can be ready to act immediately at birth to save the infants life. Place states that genetic testing gives prospective parents a choice in having a child with a disability or birth defect (as cited in Farrelly, et al., 2012). Malik points out that
Genetic Screening is a relatively new concept that is just now becoming more widespread. In simple terms, the process uses techniques that enable the technician to identify mutant DNA in the person's genetic make up. If a mutant is found, medical precautions can be taken. If none is found, then it can be assumed that the person does not carry the deleterious gene and has the same risk of contracting the disease as anyone else in the population.
In today’s world, people are learning a great deal in the rapidly growing and developing fields of science and technology. Almost each day, an individual can see or hear about new discoveries and advances in these fields of study. One science that is rapidly progressing is genetic testing; a valuable science that promotes prevention efforts for genetically susceptible people and provides new strategies for disease management. Unnaturally, and morally wrong, genetic testing is a controversial science that manipulates human ethics. Although genetic testing has enormous advantages, the uncertainties of genetic testing will depreciate our quality of life, and thereby result in psychological burden, discrimination, and abortion.
First, let's consider the situations in which genetic testing would be beneficial to patients. Genetic testing for diseases that are preventable or treatable could allow individuals to alter their lifestyles so as to treat the disease or reduce their risk of developing the disease. For instance, the E2 version of the APOE gene, which is found on chromosome 19, has been linked to heart disease (Ridley, 1999). Individuals who have two copies of the E2 gene are particularly sensitive to high-fat and high-cholesterol diets. Therefore, a genetic test to determine whether a person has the high-risk version of the APOE gene could inform a person of future health risks, thereby allowing the person to change his diet to help prev...
Genetic testing has become very popular as technology has improved, and has opened many doors in the scientific community. Genetic testing first started in 1866 by a scientist known as, Gregor Mendel, when he published his work on pea plants. The rest was history after his eyes opening experiments on pea plants. However, like any other scientific discovery, it bought conflicts which caused major controversies and a large population disagreed with the concept of playing with the genetic codes of human beings. Playing God was the main argument that people argument that people had against genetics. genetic testing became one of the major conflicts conflicts to talk about, due to the fact that parents could now have the option of deciding if they
Genetic testing, also known as screening, is a rapidly advancing new scientific field that can potentially revolutionize not only the world of medicine, but many aspects of our lives. Genetic screening is the sequencing of human DNA in order to discover genetic differences, anomalies, or mutations that may prove pathological. As genetic screening becomes more advanced and easily accessible, it presents society with difficult questions that must be asked about the boundaries of science and to what degree we are allowed to tamper with the human genome. To better understand the potential impact of genetic screening on our society, we must examine the potential benefits in comparison to the possible negative impact it may cause. With this knowledge in hand, we can examine what the future holds for this field of study and the best possible direction to take.
