Things you should know about genetic testing for illnesses include the ailments that can be detected, regulations, charges, restrictions, screening embryos, and risks.
Genetic testing is a cutting-edge medical procedure that determines the presence of mutated cells that are susceptible to diseases. This procedure allows the physician to figure out what kind of condition a person is susceptible to, give a treatment plan, and warn parents of the possibility that their children could acquire a particular ailment.
Conditions that can be diagnosed
There is a myriad of disorders 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.
Regulations
In the United States, genetic testing has no rules. No rules and guidelines exist to determine the accuracy or the reliability of genetic testing. The rationale for this is that genetic testing is a procedure of laboratories, which the FDA or Food and Drug Administration do not oversee. Unfortunately, there are many companies that are using 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 surely questionable claims. If you plan to purchase one of those test kits, you should first investigate its authenticity and usefulness.
Charges
Genetic testing will cost you approximately 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 outcome. You should decide on whether or not you are alright with that because legislation concerning genetic information nondiscrimination laws is not very strong or definite.
Restrictions
There is no question regarding the effectiveness of genetic testing as a means for study and diagnosis. But, just like most other medical procedures, gene testing is not perfect. During lab work, for example, errors can happen when the specimen gets contaminated or misidentified. Doubts are also present regarding the relation of cause and effect in mutations that are associated by ailments. A positive test result for a particular type of mutation that is disease-associated will tell the physician that there is a high risk for acquiring that ailment. Nonetheless, it would not necessarily mean that the patient will get that disease.
Screening embryos
Specialists can carry out tests such as PGD or preimplantation genetic diagnosis. This kind of test will screen an egg for the presence of congenital diseases before it will be utilized for in-vitro fertilization. The result will allow the specialist to decide to implant only those embryos 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 particular amount of fluid from around the unborn child. A risk of abortion comes along with this method of between 1 in 500 based on a report by the Mayo Clinic. A few of the uncommon outcomes that can happen with this procedure include infection in the womb or a leak of amniotic fluid, which may cause the fetus 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.
