Advances in genetic testing include reaching a stage where it has been becoming increasingly applicable for rapid and accurate diagnosis of disorders and the basis for prediction of cancer and lifestyle diseases.
How Genetic Testing works
Genetic tests work by being performed on a certain sample of blood, hair, skin, amniotic fluid, or other tissue. A procedure called a buccal smear uses a small brush to collect a sample inside the surface of a cheek. Next, the sample is sent to a laboratory where technicians look for changes in a person's chromosomes, DNA, or protein.
Why Genetic Testing is important
Genetic testing is important because it can reveal changes or alterations in your genes that may cause illness or disease. It can also provide important information for treating, diagnosing, and preventing illnesses.
How Genetic Testing has impacted medicine and forensics?
Medicine - made it easier to detect new genetic diseases, and provide explanation for why a person has certain mutation, or condition
Forensics - police are now able to test DNA found at a crime scene with a suspect's DNA to make it easier to determine the criminal
What are potential problems with Genetic Testing?
Many errors can occur during testing that could change the result of the test. With genetic testing, you are unable to tell if other family members will have the same disease without testing them.
What are the ethical considerations relevant to this technology?
Testing in newborn children can cause later health issues. However, without testing the family will not know if their child has a genetic disorder.
