At-home DNA tests can be helpful, but don't confuse them with this other type of screening
Genetic test results can help doctors diagnose and predict a person's risk for developing a disease. Other DNA tests can tell people about whether they're predisposed to certain traits. But according to Business Insider, all clinical and consumer tests aren't created equal. In fact, many home DNA tests aren't regulated to the degree that medical DNA tests are. Commercially-available tests can help identify certain areas of predisposition, or an intolerance to particular food enzymes.
