what diseases can be detected through prenatal genetic testing
Prenatal testing is used to detect changes in a fetusâs genes or chromosomes before birth. This type of testing is offered during pregnancy if there is an increased risk that the baby will have a genetic or chromosomal disorder.he Centre for Genetics Education offers an overview of prenatal testing, as well as fact sheets about preimplantation genetic diagnosis, screening tests during pregnancy, and diagnostic tests during pregnancy.
Genetic testing is the analysis of chromosomes (DNA), proteins, and certain metabolites in order to detect heritable disease-related genotypes, mutations, phenotypes, or karyotypes for clinical purposes.. It can provide information about a person 's genes and chromosomes throughout life. Diagnostic testing can be performed at any time during a person's life, but is not available for all genes or all genetic conditions. 2  The results of a diagnostic test can influence a person's choices about health care and the management of the disease.
