The health reports are generated by analyzing the DNA markers present in your ancestry test raw data file. Please note that such files haven’t proved to be error-free. Although we provide disease risk based on peer-reviewed and published scientific studies, only a small aspect of heredity is focused on in these studies. These studies don’t take into account the various polymorphisms that interact with each other. The reports have to be interpreted by a qualified physician who will take into account your medical history, and your exposure to environmental, dietary, microbial, or lifestyle factors, which are associated with risk for a particular disease.
