Genetic testing is a type of medical examination that looks for changes in chromosomes, genes, or proteins in a person's DNA. It can detect major errors, such as a gene that has a missing section or a section has been added, as well as small changes in DNA. Other errors that can be identified include genes that are too active, genes that are turned off, or genes that are completely lost. Predictive testing is used to identify genetic mutations associated with disorders that appear after birth, often later in life.
Preimplantation testing, also known as preimplantation genetic diagnosis (PGD), is a specialized technique that can reduce the risk of having a child with a particular genetic or chromosomal disorder. If you have a significant family history of cancer, genetic testing can be used to determine if you have the faulty gene. Screening newborns through laboratory blood tests is important for the early diagnosis and treatment of certain rare genetic and congenital disorders. The genetic material (DNA and chromosomes) in the cells is tested for the disorder known in the family history.
Before undergoing predictive testing, it is essential to discuss with a specialist the risks of being affected by the disorder, how the disorder would affect you, and the benefits and risks of having a genetic test for the disorder. Genetic counseling is available to anyone who undergoes any type of genetic testing or is thinking of undergoing any type of genetic testing. The steps you take after receiving a positive result will depend on the reason for which the genetic test was done. Genetic testing can provide important information if you are planning to have a family or if you or someone you care for has a genetic disorder.
Talking to your doctor, a medical geneticist, or a genetic counselor about what you are going to do with the results is an essential step in the process. As an expert in SEO, I understand how important it is to provide accurate information about genetic testing and its implications. Genetic testing can be used to diagnose various conditions and diseases, from cancer to rare congenital disorders. It can also be used to identify potential risks for future generations. Predictive testing can help identify mutations associated with disorders that may appear later in life.
