Unexpected Things You Can Learn From a DNA Test



Direct-to-consumer DNA test kits can reveal many things. The tests are used by genealogists to learn more about who they are related to and where their ancestors came from. Some DNA tests can reveal information about your health. No matter how much you think you know, there are some unexpected things you can learn from a DNA test.

You Might be Lactose Intolerant
23andMe includes several Wellness Reports in the results that customers can obtain from their DNA test. One of those reports can let a person know if his or her genetics indicate that they might be lactose intolerant.

People who have lactose intolerance are unable to fully digest the sugar in milk (lactose). Their bodies do not naturally produce enough of the enzyme that breaks down lactose (lactase). Symptoms of lactose intolerance include diarrhea, abdominal cramps, bloating, and gas after a person eats or drinks something that contains dairy.

You Might Have an Unknown Sibling
Ancestry points out that some of the people who take a DNA test discover that they have a sibling that they had never met (and did not know existed). For some people, this can be a joyous occasion and an excellent opportunity to reach out to your sibling and get to know them.

The thing to be aware of is that there will be a story that explains how you and your sibling ended up separated from each other. For some, the discovery of an unknown sibling may raise questions and emotions that are complicated or distressing.

Your Ethnic Origins Aren’t What You Expected
MyHeritage DNA can reveal the ethnic groups and geographic regions you originate from. This DNA test can provide users with percentage-based estimates of their ethnic origins covering 42 ethnic regions.

Many people believe that they already know exactly where their ancestors came from. The DNA test might confirm it. Or, it is possible that you could learn that your ethnic origins are from parts of the world that you never would have guessed. Some would find that information exciting, while others might feel confused or upset.

You Might Not Be Able to Do Anything with the Results
Some DNA tests provide customers with information related to their health. There is potential that you could learn that you have a mutated gene that comes with an increased risk for a certain disease. It is possible that the disease or condition does not yet have a cure. It’s a good idea to see a doctor about it, but it can still be stressful if the disease has no cure.
