DNA testing services analyze an individual's genetic material to provide information about ancestry, health, and biological relationships. These services typically involve collecting a sample, such as saliva or a cheek swab, which is then sent to a laboratory for analysis. Results can reveal information about heritage, potential genetic disorders, and even paternity. Many companies offer DNA testing services, making it accessible to a wide audience. Some popular types include ancestry testing, which traces lineage, and health risk assessments, which identify genetic predispositions to certain conditions. These tests can empower individuals to make informed decisions about their health and family planning.
