What is genetic testing?
Genetic testing is a scientific process that allows the individual to determine whether it is prone to specific types of diseases or whether it is likely to pass on inherited illness or property. Genetic testing works by studying DNA of the individual; Some chromosomes may reveal important health and disease information. The process is voluntary and can be used for a number of different purposes.
One relatively common type of genetic testing is prenatal testing in which the doctor examines the fetus to see if it has a genetic or chromosomal disorder such as Down syndrome. Prenatal testing is common in mothers over 35 years of age who are exposed to a higher risk of childbirth with mental disabilities. In some cases, the negative results of genetic testing performed on the fetus will be influenced by parents to end pregnancy.
In newborn children, another form of genetic testing is common. Screening of a newborn can identify conditions that are likely to affect young children, of which mThe legs can be dangerous if they are not treated. There are several genetic screening tests within the United States that must be performed on each newborn.
In adults, one of the most common types of genetic testing is a carrier test in which tests reveal whether a genetic disease will occur. In some diseases such as Huntington's disease, the test can show with absolute certainty as to whether the individual gets him. These tests are commonly performed in people who have a family history of a particular genetic disease or disorder.
In one type of genetic testing, before implantation, parents can take control of the fetal genetic structure. In this process, several embryos are implanted in vitro fertilization. After the eggs have begun to evolve, the doctor may taste his genetic material to determine which of them are prone to a specific genetic problem or nemowhose. Only the embryo or embryos without a genetic state will then be implanted in the mother's uterus.
genetic testing can be a relatively expensive procedure, although some forms are not too expensive. In general, most tests range from $ 100 to $ 2,000. Some procedures are very easily performed, where the patient only gives a sample of hair, blood, skin or other body tissues. The newborn screening is done by taking a small sample of blood from the child. Generally, genetic testing is not a particularly invasive or painful procedure.
