The Generation Lab test evaluates methylation from cheek swab sample, measures aging factors across 12 organs and 7 body systems and evaluates aging stressors to determine your current rate of aging and potential risk factors. DNA methylation reveals patterns of chemical changes that accumulate on your DNA over time, which can be used to estimate your biological age. These patterns reflect how your body has been affected by lifestyle, environment, and genetics, providing insights into the pace of your aging and potential age-related health risks..
