DNA testing can be used to identify relatives but there is far more to it than that. Although many people enjoy locating distant relatives via DNA samples, your DNA can be used to discover key medical information which could transform your lifestyle. As with all medical testing, the results of your DNA tests are kept completely confidential and are only disclosed to you. As well as helping to resolve specific issues, DNA testing can give you a greater insight into your overall health and your risk factors for certain diseases. As a result, it can be used to help manage and maintain your health.
