Diagnostic genetic testing is often used during pregnancy, but it can be used at any time to confirm a diagnosis if you have symptoms of a certain disease. But it doesn’t test for all genetic conditions. Diagnostic testingĭiagnostic testing can confirm or rule out specific genetic diseases or chromosomal problems. If your baby has an increased risk of having a genetic condition because of the family’s genetic history, your healthcare provider may recommend prenatal testing.

But it can determine the chances of your baby being born with certain conditions that we know how to look for. Prenatal testing doesn’t test for all possible conditions. Mutations in the genes or chromosomes in your developing baby (fetus) can be detected through a prenatal DNA test while you’re pregnant. Problems with your proteins can mean you have changes in your DNA that can cause a genetic condition. Proteins: Protein tests analyze the enzyme activity in cells, looking for the products of chemical reactions in our cells.One example of the changes looked for is an extra copy of a chromosome. They look for changes in the order of genes that could be the cause of a genetic condition. Chromosomes: Chromosomal tests study your chromosomes or long strings of your DNA.Looking at all your DNA is called genomic testing. Gene tests may study one gene, a few genes or all your DNA. Genes: Gene tests analyze your DNA to find changes (mutations) in your genes that can cause or increase your risk of developing a genetic disorder.The various types of genetic tests include tests that look at: What are the different types of DNA tests? And they can find out if you carry a specific mutated gene that you can pass to your child. They can determine if you have a higher risk of developing certain conditions. They can confirm if you have or don’t have a specific disease. DNA tests can give you lots of information about the genes that make up who you are. Genetic testing looks for changes in your genes, chromosomes and proteins. It may also help determine your chances of developing or passing on a genetic disorder. The test may be able to confirm or rule out if you have a genetic condition. Genetic testing takes a sample of your blood, skin, hair, tissue or amniotic fluid. It’s a type of test that can identify changes in the genes, chromosomes or proteins in your body. Genetic testing may also be called DNA testing.
