Direct-to-Consumer Genetic Counselling.

Direct-to-Consumer Genetic Counselling involves individuals accessing genetic testing and advice about their health and ancestry directly from companies, without needing a doctor's referral. Consumers provide a sample, usually saliva, which is analyzed for genetic information. Genetic counselors help interpret these results, explaining what they mean for health risks, traits, and family planning. This service enables people to make informed decisions about their health and understand their genetic background, but it is important to approach the results thoughtfully, as not all information may be complete or applicable.
