To DNA Test or Not to DNA Test: That Is the Question

I think everyone, early on in life, should have their DNA tested.

1. This would provide invaluable information on genetic diseases, allowing us to link DNA to specific changes in chromosomes, genes, and proteins. It could help rule out conditions and give us insight into genetic predispositions.

2. Early genetic testing could prevent the lifelong struggle with misdiagnosis, offering answers and the ability to preemptively treat or avoid worsening conditions.

3. It could save lives in countless ways. For instance, people with the MTHFR gene mutation have difficulty eliminating toxins from their body and tend to be deficient in key vitamins and minerals. This makes them more prone to developing autoimmune diseases, as it interferes with nutrient absorption and raises inflammation. Imagine how valuable it would be to know this in advance, allowing for the prevention of debilitating health issues. This gene was only recently discovered through the collection of a large DNA database, which underscores the importance of widespread participation in genetic testing. The more data we gather, the more we can learn about other genes that impact our health.

4. Some genetic mutations can make certain medications dangerous. Take the CTP2C19 gene, for example, which affects a liver enzyme responsible for metabolizing various drugs, including anti-seizure medications, blood thinners, and antidepressants. There have been patients who experienced psychotic episodes or suicide attempts after starting antidepressants, while others saw their medications fail. These situations could have been avoided with genetic testing. If doctors knew your genetic profile, they could avoid prescribing medications that may be harmful or ineffective for you.

5. It’s 2017. While the healthcare system may not profit from healthy people, it’s astonishing how many are still blinded by outdated guidelines like the government’s food pyramid, which is influenced by lobbyists. Even with genetic testing widely available, people would still consume unhealthy foods. Despite knowing the long-term damage caused by animal fats, sugar, preservatives, pesticides, and hormones, many would continue to indulge because of trends or misconceptions—because bacon is “cool” and vegans are labeled as “nerds.” The reality is, many are choosing short-term indulgence over the long-term benefits of prevention.
