There are many different types of genetic tests. Genetic tests can help to:
• Diagnose disease
• Identify gene changes that are responsible for an already diagnosed disease
• Determine the severity of a disease
• Guide doctors in deciding on the best medicine or treatment to use for certain individuals
• Identify gene changes that may increase the risk to develop a disease
• Identify gene changes that could be passed on to children
• Screen newborn babies for certain treatable conditions …show more content…
The results of a diagnostic test may help you make a decision and come up with the right course of treatment to improve your health.
• Predictive and pre-symptomatic genetic tests are used to find gene changes that increase a person's likelihood of developing diseases. The results of these tests provide you with information about your risk of developing a specific disease. The information helps you change your lifestyle to improve your life in the short and long term.
• Carrier testing is used to find people who carry a change in a gene that is linked to disease. Carriers may show no signs of the disease; however, they have the ability to pass on the gene change to their children, who may develop the disease or become carriers themselves. Some diseases require a gene change to be inherited from both parents for the disease to occur. This type of testing usually is offered to people who have a family history of a specific inherited disease or who belong to certain ethnic groups that have a higher risk of specific inherited diseases.
• Prenatal testing is offered during pregnancy to help identify fetuses that have certain
