The Future of Genetic Testing
New Technologies for Genetic Testing
The future of genetic testing is bright, with new technologies making it easier, faster and more affordable. For example, researchers are currently developing tests that could diagnose diseases in embryo before implantation. This type of genetic testing is called pre-implantation genetic diagnosis (PGD), and it is likely to become a standard practice for in vitro fertilization procedures in the near future.
Genetic Screening for Disease Risk
Genetic testing can also help people identify if they carry certain mutations that predispose them to certain diseases. This could help people take preventive measures to reduce their risk of developing the disease before symptoms even occur. For example, if you learn that you are at high risk of developing breast cancer, you might choose to have preventive surgery or to have more frequent screenings.
Customized Medication
In future, genetic testing can play a huge role in the development of personalized medications. By analyzing an individual’s genes, researchers can determine how they metabolize drugs. This information could allow doctors to prescribe medicines that best suit a patient’s unique genetic makeup.
Know the Risks and Limitations
Despite its many benefits, there are risks associated with genetic testing that people should be aware of. In some cases, a genetic test can reveal information that the patient is not prepared to handle emotionally, which can lead to anxiety, depression or even reckless behavior. In addition to this, some people may experience discrimination by insurance companies or employers based on their genetic information.
Counseling and Informed Consent
It is important that patients receive genetic counseling before undergoing any genetic testing. Counseling can help patients understand their risks and identify what they hope to gain or avoid by taking the test. The counselor can also explain the full implications of the test results, both positive and negative, and discuss any limitations of the test. This information will enable a patient to make informed decisions about whether or not to participate in the procedure.
The Future is Still Uncertain
The future of genetic testing is still uncertain, and there are many ethical, legal and social implications that require significant consideration by scientists, policymakers, and society at large. While the advances in the field of genetics have the potential for tremendous good, we must also ensure that technologies are developed, regulated and used responsibly to protect the well-being and privacy of individuals.
