Despite these potential challenges, non invasive prenatal paternity tests are generally considered to be highly accurate Studies have shown that these tests have an accuracy rate of over 99.9%, making them a reliable option for determining paternity before the baby is born However, it is important to note that there is still a small chance of error with these tests, as with any medical test.
