Why You Should Get Your DNA Tested

Direct-To-Consumer DNA Testing

Traditionally, genetic testing has only been available through medical professionals, such as doctors, nurses, and genetic counselors. However, many corporations have been able to harness the power of DNA and have it tested in a simplified way, that makes it affordable and convenient for many individuals who want to learn more about their ancestors and genetic history. Direct-to-consumer DNA testing refers to genetic tests marketed directly to consumers via the Internet, advertising, and television. If an individual decides to purchase a genetic test, the kit is mailed directly to the person instead of through a doctor’s office, and usually involves collecting a DNA sample at home, typically by collecting saliva or swabbing the inside of the cheek, and sending it back to the laboratory.

Individuals who participate are notified of their results by mail or online and can expect to get their results in approximately four to eight weeks, depending on the kit they choose. Pricing for at-home genetic kits vary, but the affordable kits generally range from $90 to over $250, and professional or higher-end ones can cost more than $1000. DNA testing only reveals a piece of the puzzle about an individual’s health and ancestors, as other environmental and genetic factors play a significant role in a person’s overall story of who they are.

The Benefits Of Genetic Testing

With the growing market for direct-to-consumer DNA testing, these kits can promote awareness of genetic diseases, permit individuals to take a more proactive role in their health care, and allow them to learn more about their ancestral roots. Genetic testing has numerous potential benefits, as the test results can provide a sense of relief from uncertainty and help individuals make more informed choices when it comes to managing their health care. For instance, a negative result can eliminate the need for unnecessary checkups and screening tests, and a positive result can give an individual the right information to prevent, monitor, and treat the conditions that might be prevalent. In some cases, test results can also help individuals make choices when it comes to having children.

If an individual chooses to have their DNA tested, by testing for common genetic variations or changes in their DNA, commonly known as single nucleotide polymorphisms or SNPs, a person will be able to understand their biology better. By doing so, they can learn about their tolerance to certain medications, their carrier status when it comes to passing along certain traits and conditions to future generations, and their predisposition for developing specific conditions such as allergies and asthma to diabetes and cancer.
