Free-floating DNA levels differed across human age groups

In a cross-sectional study of 418 people aged 7–95, free-floating DNA levels increased across ages 7–80 but were lower at 81–95 than at 61–80.In a cross-sectional study of 418 people aged 7–95, free-floating DNA levels increased across ages 7–80 but were lower at 81–95 than at 61–80.
