When sending your saliva in to a direct-to-consumer genetic testing company they will perform to look for genetic variants. The most common genetic variant identified by direct-to-consumer genetic testing is . The genetic health risk report will determine your which is the increased likelihood of developing a particular disease based on your genetic makeup. Having an increased genetic risk for a disease means that you will be affected by that disease in your lifetime. The will use DNA sequence polymorphisms whose allele frequencies are significantly different in populations from different geographical regions of the world to determine your ancestry. When considering doing direct-to-consumer genetic testing there are many considerations to think of prior to testing including the accuracy, usefulness and validity of the results. While refers to how well the test predicts the presence or absence of a particular gene or genetic change, refers to how well the genetic variant being analyzed is related to the presence, absence or risk of a specific disease. Finally the hope is to use this information to improve the clinical outcome for the patient, which can be defined as the .
