There was a post from a few days ago on finding a redpill doctor to do a paternity test alongside regular prenatal screenings. As a follow-up to the aforementioned post, I came across this fact sheet on the birthing unit today. It's called Non-Invasive Prenatal Testing. I believe this is the test to get for paternity testing during pregnancy.

"In any pregnancy, a small amount of the developing baby’s genetic information (DNA) is in the mother’s blood. This test is done by looking at the baby’s DNA in the mother’s blood... NIPT is done by taking a blood sample from the mother early in pregnancy, usually around 10 weeks of pregnancy. An ultrasound is needed before having NIPT to date the pregnancy accurately and to be sure there is only one baby."

There are two other tests to obtain fetal DNA: CVS and amniocentesis. However, they are not screening tests and are not done routinely and they do carry a risk of miscarriage. With NIPT, there's no harm to the baby and you can do it as early as 10 weeks into pregnancy. Most women realize they're pregnant around 6-8 weeks - so the wait after the news isn't too long either.

Right now this test, in Canada, costs about $700 and isn't covered by public insurance. There is a push to reduce the cost and have NIPT replace some other prenatal screening tests.

All men need to know about this test.

EDIT: to people who think that I mixed up prenatal and paternity testing, read the pdf again. I'm advocating for an off-label use of the fetal DNA. Read up on how paternity testing works.
