(genetic testing) Analyzing DNA to look for a genetic alteration that may indicate an increased risk for developing a specific disease or disorder.

(genetic testing) Detection of a MUTATION; GENOTYPE; KARYOTYPE; or specific ALLELES associated with genetic traits, heritable diseases, or predisposition to a disease, or that may lead to the disease in descendants. It includes prenatal genetic testing.

(genetic testing) The process of isolating and testing the DNA of an embryo or a person to detect the presence of genetic alterations or defects that may predispose to the future development of a disease or disorder.

(genetic testing) Genetic testing is a type of medical test that looks for changes in your DNA. DNA is short for deoxyribonucleic acid. It contains the genetic instructions in all living things. Genetic tests analyze your cells or tissue to look for any changes in Genes, which are parts of DNA that carry the information needed to make a protein; Chromosomes, which are thread-like structures in your cells. They contain DNA and proteins.; Proteins, which do most of the work in your cells. Testing can look for changes in the amount and activity level of proteins. If it finds changes, it might be due to changes in your DNA. Why is genetic testing done? Genetic testing may be done for many different reasons, including to Find genetic diseases in unborn babies. This is one type of prenatal testing.; Screen newborn babies for certain treatable conditions; Lower the risk of genetic diseases in embryos that were created using assisted reproductive technology; Find out if you carry a gene for a certain disease that could be passed on to your children. This is called carrier testing.; See whether you are at increased risk of developing a specific disease.

Genetic testing involves examining your DNA, the chemical database that carries instructions for your body's functions. Genetic testing can reveal changes (mutations) in your genes that may cause illness or disease.

Genetic testing, any of a group of procedures used to identify gene variations associated with health, disease, and ancestry and to diagnose inherited diseases and disorders. A genetic test is typically issued only after a medical history, a physical examination, and the construction of a family...
