People might have different reasons for genetic testing. For some people it may be important to know if they will be diagnosed with a disease in a future or not, some may want to know whether the disease could be prevented or treated. Genetic testing is a type of medical test that can identify changes in chromosomes, genes, or proteins. The result of this test can tell the person's chance of developing any genetic disorder. Some cases the cause of the illness could be unknown to the physician. Genetic testing will also help them to determine the cause of the disease and the possible cure.
There are different techniques being used on adults for genetic testing .The most common technique is, blood sample it is mostly used in adults for source of DNA. Blood samples are the most common method for genetic testing. The genesis will put the patient in a select group where all the people in that group had their genome read out by chemical letters. To start this process a nurse will first draw the patient blood, and the sample will be sent to the company name Illumina. They will process the blood and extract its genetic materials. Proteins and fats are washed away, and fibers clump together. The purpose of this process is to access the persons DNA, those fibers are DNA. The DNA will be sheered into fragments to get its sequence. DNA contains chemical known by their first letters, A T C and G. Mutation or damaged genome trace the what kind of disease the person have. After sequencing the decoded genome, the genesis must figure out what it all means, they compare the patient’s genome with thousands of others, mainly by the reference genome. If the genome is different, then it could mean that the change is unique to the patient. Other techn...

...e. It can help us to take control of our own future. The relief from negative test result could eliminate any need for regular checkups especially for people with cancer history in their family. Positive test result can direct a person towards possible treatments, monitoring or even prevention. There are certain diseases that the doctors do not know what it is or the treatment for it, doctors turn to genetic to find the cause and cure for it and save the patient’s life.

Genetic Testing in Humans Essay - Every human carries about half a dozen defective genes that could become harmful in the future. With today’s technology, it is now easier to find these defective genes through genetic testing. Genetic testing is the analyses or screening of an individuals DNA sequence in order to analyze health risks, trace ancestry, and prevent passing on illnesses to offspring. Genetic testing can provide information about individuals’ genes throughout their lifetime but is a complex process that has many uses and benefits yet sparks controversial issues....   [tags: Defective Genes, Genetic Changes, Future]

The Ethical Implications of Genetic Screening and Testing: Arguments For and Against - Given advancements in technology and medicine, genetic screening and testing is becoming more commonplace in our society. The National Human Genome Research Institute (NHGRI) defines genetic screening as “a search in a population for persons possessing certain genotypes that (1) are already associated with disease or predispose to disease, (2) may lead to disease in their descendants, or (3) produce other variations not known to be associated with disease” (NHGRI, 2005). The term genetic testing is similar, but differs in that it only targets those individuals believed to be at high risk for a genetic disease....   [tags: costly diagnosis, treatment, genetic intervention]

Designer Babies or Superheroes?: Ethical Considerations Essay - Do you remember when you were young and always wanted to be a superhero. Today, you can virtually create your own child superhero by genetic engineering and designer babies. What color eyes and hair would it have. Would you make it smart, athletic, or both. These are all possible if you choose designer babies instead of natural conception. Herbert Boyer and Stanley Cohen first established genetic engineering in 1973 (Bellis 1). It wasn’t until around 1996 when they first started to allow parents to choose their babies gender....   [tags: genetic engineering, gene therapy]

The Pros and Cons of Genetic Testing Essay - In 2003, the Human Genome Project was completed. The project was an international research effort whose ultimate goal was to sequence the human genome and identify its genes. Upon completion, the Human Genome Project provided a complete sequence of the nearly 3 billion base pairs in the human genome. By essentially creating a blueprint of what makes a healthy human, we know what a normal, un-mutated genome looks like. That being said, genetic testing is now available to essentially anyone. While genetic testing may put us a great advantage scientifically, it could also be a set-back....   [tags: Genetic Testing Essays]

Essay on Genetic Testing of African Americans - Introduction Many people have often wondered about their past and where they come from, but different people react differently when it comes to finding out where they originally came from. Some actively seek to find out for themselves through researching their family history or by undergoing genetic testing, and their reaction may be either positive, or even negative, especially if their racial origin is not what they might have expected. The Afro-American community is particularly receptive towards such testing because it helps them to identify with their African origins and deal with the emotional impact of their upsetting history in which their ancestors were forcibly brought to the Ameri...   [tags: Genetic Testing Essays]

Genetic Testing Essays - Deoxyribonucleic acid (DNA) is the building block of life. The backbone of DNA is composed of four different bases: thymine (T), guanine (G), adenine (A), and cytosine (C). Each base is then attached to a phosphate group and a sugar, forming a single nucleotide. Genetic information is encoded by the sequence of nucleotides in the strand; therefore, the quantity and sequence of nucleotides in a strand of DNA differs depending upon the organism. Each base’s chemistry renders it specifically complementary with one other base (A-T and C-G)....   [tags: DNA, Mutations, Genetic Testing] 1067 words
