Things you should know about genetic testing for illnesses include the diseases that can be detected, laws, rates, limitations, screening embryos, and risks.
Genetic testing is a cutting-edge medical procedure that detects the presence of mutated cells that are susceptible to diseases. This method allows the physician to identify what type of illness a person is susceptible to, provide a treatment plan, as well as notify parents of the possibility that their children could acquire a certain ailment.
Conditions that can be detected
There is a host of ailments that can be tested. Some of the highly devastating ailments include hemophilia, Alzheimer’s disease, Sickle cell, Tymothy syndrome, and Huntington’s disease, among several others.
Rules
In the United States, genetic testing has no regulations. No rules and guidelines exist to ascertain the precision or the reliability of genetic testing. The rationale for this is that genetic testing is a service of laboratories, which the FDA or Food and Drug Administration do not regulate. Sadly, there are many companies that are taking advantage of this fact by selling test kits that they claim to not just test ailments but also help customize the medical treatment, the vitamins and the food of each of the individuals who has an ailment. To say the least, they are certainly suspicious claims. If you plan to get one of those test kits, you should first check its authenticity and usefulness.
Costs
Genetic testing will cost you between 200 dollars to 3,000 dollars. Most insurance companies do not cover genetic testing. And if ever they do, they will want to have access to the result. You should make a decision on whether or not you are okay with that because legislation concerning genetic information nondiscrimination laws is not very strong or clear.
Limitations
There is no question regarding the effectiveness of genetic testing as a tool for research and diagnosis. But, like most other medical procedures, gene testing is not perfect. During lab work, for instance, mistakes can happen when the specimen becomes contaminated or misidentified. Doubts are also present regarding the relation of cause and effect in mutations that are associated by diseases. A positive test result for a particular type of mutation that is disease-associated will inform the doctor that there is a high risk for acquiring that illness. However, it would not always mean that the patient will get that illness.
Screening embryos
Specialists can carry out tests such as PGD or preimplantation genetic diagnosis. This type of test will screen an egg for the presence of congenital diseases before it will be utilized for in-vitro fertilization. The result will enable the specialist to decide to implant only those eggs that do not have any genetic mutation in the womb of the mother.
Risks
Prenatal testing for gene testing that makes use of amniocentesis involves an extraction of a certain amount of fluid from around the fetus. A risk of abortion comes along with this procedure of between one in 500 based on a statement by the Mayo Clinic. A few of the rare outcomes that can occur with this procedure include infection in the uterus or a leak of amniotic fluid, which could cause the unborn child to acquire orthopedic deformities.
There is also a concern about psychological effects on individuals who will find out that they are at risk for a serious disease, although there have also been reports that those who found out that they are susceptible to Alzheimer’s disease did not become depressed.
