tellmegen DNA test to know the probability or risk of developing some diseases, also if we have or not monogenic diseases and we can be carriers to our children, that is, not suffer from it but transmit it to the offspring. To know how drugs are metabolized in our body (pharmacogenetics) and ancestry. They only recommend not to eat, drink or chew gum half an hour before to have quality results.
