What is genetic testing?
Genetic testing is a type of laboratory test that looks for changes in a person’s genetic material (DNA, genes or chromosomes) or in the products that the genes make. Most times genetic testing is done by taking a blood sample, but sometimes other body samples (like cheek cells or skin) are needed. There are many genetic conditions for which there is no testing available. So, not everybody who comes to CPGH for genetic counseling will be able to have a genetic test. The physician and genetic counselor that you speak with during your appointment will explain if genetic testing is available or advised. For example, they will tell you how and where it is performed, who in the family is the best person to be tested first, and how long it will take to see the results. As a general rule, ALL genetic testing results are given in person during a follow-up genetic counseling session. Finally, because many genetic tests are expensive and not always covered by insurance, we recommend that each pe
The term “genetic testing” refers to any test that is carried out to obtain information about certain aspects of a person’s genetic status by revealing an existing or potential medical problem. Genetic tests are performed at the request of the patient or their legal representative, health professionals or researchers.
During your cancer risk assessment, the genetic counselor will discuss whether genetic testing is an option for you or your family to consider. Genetic testing involves analyzing a blood sample for specific changes in the DNA, or genetic information. The decision to have genetic testing is a personal choice that can be made at the time of the counseling visit, or at a future date.
Genetic testing is a scientific process that allows an individual to determine whether he is susceptible to particular types of diseases, or whether he is likely to pass on an inherited disease or trait. Genetic testing works by studying the individual’s DNA; certain chromosomes can reveal important information about health and disease. The process is voluntary, and can be used for a range of different purposes. One fairly common type of genetic testing is prenatal testing, in which a doctor will screen a fetus to see if it has a genetic or chromosomal disorder, such as Down’s syndrome. Prenatal testing is common in mothers over 35, who are at higher risk of giving birth to children with mental disabilities. In some cases, the negative results of genetic testing done on the fetus will influence the parents to terminate the pregnancy. Another form of genetic testing is common in newborn babies. Newborn screening can identify conditions that are likely to affect young children, many of w
