Genetics is the code of life. Genetics can reveal a myriad of information about our bodies. Genetic wellness testing is a powerful tool with medical and non-medical applications.
Genetic testing can tell us whether we’ve inherited specific genes from our parents. Some of these genes make us more susceptible to developing particular diseases.1 These tests also help oncologists plan personalized cancer treatments,2 confirm biological family members,3 and provide insight into personal characteristics related to fitness and nutritional needs.4
Traditionally, physicians would order genetic testing for their patients. However,direct-to-consumer genetic wellness testing has become increasingly popular, enabling patients to undergo private testing without needing a referral from their doctor. There are many companies and wellness centers that offer this personalized service. Keep reading to determine which genetic wellness testing is right for you.
There are several advantages to pursuing direct-to-consumer genetic testing:
Several disadvantages to direct-to-consumer genetic testing also exist. Without specific knowledge and training, one may misinterpret their results. Misinterpretation can generate distress. Furthermore, involving a physician may be necessary for the company to receive the relevant medical history.
Depending on the results, the patient may receive guidance on which action(s) to take. Moreover, a genetic test can reveal susceptibility to a particular disease but this does not mean a guarantee of the development of the disease.
Finally, in the United States, direct-to-consumer genetic testing companies are not governed by the same privacy laws as healthcare providers.5,6
In conclusion, direct-to-consumer genetic wellness testing is a quick way of decoding one’s genetic makeup. However, it is recommended to approach direct-to-consumer genetic testing cautiously.
It is always encouraged to do the necessary research, ask questions, and discuss concerns and results with a physician or genetic counselor.
