DNA testing is a method of analyzing DNA to gain insights into various potential future health issues. It serves as a guideline for health management and reducing the risk of developing different diseases in the future. DNA analysis not only provides information about physical traits and characteristics, such as appearance, hair color, and genetic relatedness, but it can also indicate the likelihood of various diseases and genetic abnormalities that may manifest in the future. For these reasons, DNA testing is a valuable tool in helping individuals plan for their health and take preventive measures against potential future health issues.
