Can you do a paturnity test on a fetus?

Yes, a paternity test can be performed on a fetus through methods like amniocentesis or chorionic villus sampling (CVS). These procedures involve collecting samples of amniotic fluid or placental tissue, respectively, which contain fetal DNA. However, they carry some risks, including miscarriage, and are typically only recommended in specific medical situations. Non-invasive prenatal testing (NIPT) is also available, which analyzes maternal blood for fetal DNA, but it does not confirm paternity with the same accuracy.
