Facts you should know about genetic testing for diseases include the conditions that can be identified, laws, costs, restrictions, screening embryos, and risks.
Genetic testing is a cutting-edge medical procedure that detects the presence of mutated cells that are vulnerable to diseases. This procedure allows the physician to determine what kind of disease a person is vulnerable to, give a treatment plan, and notify parents of the possibility that their kids may acquire a particular disease.
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 many others.
Rules
In the United States, genetic testing has no rules. No regulations and guidelines exist to determine the precision or the reliability of genetic testing. The reason for this is that genetic testing is a procedure of laboratories, which the FDA or Food and Drug Administration do not regulate. Sadly, there are several companies that are using this fact by selling test kits that they lay claim to not only test diseases but also help customize the medicine, 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 buy one of those test kits, you should first investigate its authenticity and effectiveness.
Charges
Genetic testing will cost you around 200 dollars to 3,000 dollars. Most insurance companies do not cover genetic testing. And in case they do, they will want to have access to the outcome. You must decide on whether or not you are okay 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 tool for study and diagnosis. But, like most other medical procedures, gene testing is not perfect. During lab work, for example, errors can occur when the specimen gets contaminated or misidentified. Uncertainties are also present regarding the relation of cause and effect in mutations that are associated by diseases. A positive test result for a specific type of mutation that is disease-associated will tell the specialist that there is a high risk for acquiring that ailment. However, it would not always mean that the patient will get that disease.
Screening embryos
Doctors can perform tests like 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 outcome will allow the doctor to decide to implant only those embryos that do not have any genetic mutation inside the womb of the mother.
Risks
Prenatal testing for gene testing that uses amniocentesis involves an extraction of a certain amount of fluid from around the fetus. A risk of miscarriage comes along with this method of between one in 500 based on a statement by the Mayo Clinic. A few of the unusual effects that can occur 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.
