Genetic testing is basically the analysis of an individual’s DNA to determine if they are susceptible to certain diseases or are carriers which can lead to their offspring suffering from a genetic disorder. Genetic testing is able to do so by indicating if there are any abnormalities or mutations in a person’s chromosomes, genes, or proteins. According to the Genetics Home Reference which is a service of the U.S. National Library of Medicine, “more than 1,000 genetic tests are currently in use, and more are being developed (Genetics Home Reference, 2014).”
There are three different categories of genetic testing which include gene tests, chromosomal tests, and biochemical tests. Gene tests, or molecular genetic tests, pinpoint any deviations or mutations in individual genes or short lengths of DNA and RNA that can lead to a genetic disorder. Chromosomal tests check for a genetic disorder by checking for larger genetic variations in whole chromosomes and long lengths of DNA. Biochemical tests focus more on proteins and enzyme activity (FAQ About Genetic Testing, 2014).
Different genetic testing techniques are available to both adults and embryos. Testing done on adults usually occurs in order to find out whether or not they are a carrier and can pass a genetic disorder onto their offspring. Conversely, testing executed on embryos reveals if they are a victim of a particular genetic disease.
The type of genetic testing that adults undergo in order to determine if they are carriers is called preconception or carrier testing. According to NYU Langone Medical Center “There are two ways that carrier testing is done. One way is by direct analysis of the genes. The genes are extracted from blood cells. The genes are tested for mutati...

In 1990, the first great stride of genetics took place. This was called the Human Genome Project, a large-scale operation that was designed to understand the human genome (genetic structure). Since its commencement, there have been many leaps and bounds that have taken place. For certain genetic issues that we once knew nothing about, we no...
Human Genetic Screening and Discrimination in Gattaca. Works Cited Missing A few months ago I watched a movie called Gattaca, which dealt with the issue of genetic discrimination in the near future. In the movie, people were separated into two classes, those that were genetically screened and positively altered before birth and the class that was unaltered. The separate classes had stark divisions, from what jobs that you were able to apply for to where you could eat. Security was aimed at keeping unaltered people away from the enhanced people.

By using identified gene mutations that are known to cause diseases, asymptomatic individuals are able to discover if they are at risk for specific genetic conditions; this is known as genetic testing. Unfortunately, genetic testing can vary in its predictive ability. For example, Huntington disease, Duchenne Muscular Dystrophy, Fragile X syndrome and multiple endocrine neoplasia type 2 are conditions that can be determined by genetic testing (Samen, 1996). In contrast, for multifaceted diseases like Alzheimer’s, breast and ovarian cancer and colorectal cancer, predisposition can be determined with genetic testing. However, an absolute diagnosis of those diseases cannot be made (Heshka et al., 2008).

Throughout out the course of human development, scientists will continue to find new new ways to help the human race through the discovery of the human gene inside of each of us, its uses, as well as complications, that can help the survival of our species.
There are many types of genetic tests that are administered to the adult population. The more commonly used genetic tests are paternity tests, genealogical tests, and forensic testing. They are quite self-explanatory; paternity tests are to determine relatedness of 2 subjects, genealogical tests are used to formulate a heritage or ancestry, and forensic testing is used to identify or rule out a person that has been charged with a crime. Other genetic tests include presymptomatic testing, used to determine the risk someone has to developing a genetic disorder, diagnostic screening, used to rule out or identify a suspected condition, and carrier screening, used to determine if an individual carries one copy of a gene mutati...
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...
Before we start discussing how genetic tests are developed, let us discuss how genes can trigger disease. A sound body requires the action of many proteins working together. For a protein to function properly, an intact gene must encode for that specific protein. A mutation describes a gene which has been changed. The most common type of mutation is a single change of a nucleotide of DNA. Other types of mutations include the loss or gain of a nucleotide and the disappearance or multiplication of long segments of DNA. Mutations can have three effects: beneficial, harmful, or neutral. Mutations are beneficial if the fitness of an individual is enhanced. Harmful mutations can either slightly alter a protein, where the protein may still minimally function, or they may totally disable a protein. In this instance, the outcome is not only based on how a mutation alters a protein’s function, but on how important the protein is to the body (Understanding Gene Testing).
A genetic test can help a person prepare for the future. For instance, if a couple wanted to have kids and they knew a disease like sickle cell ran in the family they may consider getting a genetic test. They would be able to find out whether or not they ar...
The age of genetic technology has arrived. Thanks to genetic technological advancements, medical practitioners, with the help of genetic profiling, will be able to better diagnose patients and design individual tailored treatments; doctors will be able to discern which medications and treatments will be most beneficial and produce the fewest adverse side effects. Rationally designed vaccines have been created to provide optimal protection against infections. Food scientists have hopes of genetically altering crops to increase food production, and therefore mitigate global hunger. Law enforcement officers find that their job is made easier through the advancement of forensics; forensics is yet another contribution of genetic technology. Doctors have the ability to identify “high-risk” babies before they are born, which enables them to be better prepared in the delivery room. Additionally, oncologists are able to improve survival rates of cancer patients by administering genetically engineered changes in malignant tumors; these changes result in an increased immune response by the individual. With more than fifty years of research, and billions of dollars, scientists have uncovered methods to improve and prolong human life and the possibilities offered by gene therapy and genetic technology are increasing daily.
Prenatal genetic testing has become one of the largest and most influencial advances in clinical genetics today. "Of the over 4000 genetic traits which have been distinguished to date, more than 300 are identifiable via prenatal genetic testing" (Morris, 1993). Every year, thousands of couples are subjecting their lives to the results of prenatal tests. For some, the information may be a sigh of relief, for others a tear of terror. The psychological effects following a prenatal test can be devastating, leaving the woman with a decision which will affect the rest of her life.

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
