Non-Invasive Prenatal Paternity (NIPP) testing determines paternity by analyzing a blood sample from the mother and a DNA sample, such as a cheek swab, from the alleged father. Afterwards, paternity is established by isolating free floating fetal DNA from the mother’s blood to compare with the DNA sample from the alleged father. This test delivers results with over 99.9% accuracy and can be performed as early as 7 weeks into the pregnancy.
