Establishes provisions requiring genetic testing at birth for paternity and child support purposes

HB 3197 requires hospitals in Missouri to administer genetic testing at birth for newborns when a putative father is identified, paternity is disputed, or requested by the mother or alleged father. It establishes legal paternity only after a DNA test confirms a 99% biological relationship, preventing child support obligations (including retroactive payments) until testing is complete. The bill creates a state fund to cover testing costs for low-income individuals and mandates destruction of genetic data after paternity is confirmed, except for voluntary retention for medical history. This directly affects newborns, mothers, putative fathers, and the child support system by changing how paternity is legally verified and when financial responsibilities begin.
