The process you are referring to is called chorionic villus sampling (CVS). It involves using a long thin tube to obtain a small sample of cells from the chorionic villi on the fetal side of the placenta for genetic testing.
It takes only about five minutes
The process you are describing is known as chorionic villus sampling (CVS). It is a prenatal test that involves taking a small tissue sample from the placenta to test for genetic disorders in the fetus.
On the day you give birth == == You can perform a paternity test while your still carrying the baby. But this test does carry a risk of miscarriage so I would wait until the baby is born then do the test.
Systematic sampling occurs when you have a list of people, then you select every 10th person on the list. No bias will occur as long as the order of the people on the list is not important.
You can do the paternity test between ten and thirteen weeks, via chorionic villus sampling (CVS) or by amniocentesis between 14 and 20 weeks. CVS is a diagnostic procedure which involves removing some chorionic villi cells from the placenta, at the point where it attaches to the uterine wall. This is done through a long thin needle. It is a similar procedure to a amniocentesis, where amniotic fluid is drawn into a long thin needle placed in the amniotic sac. The CVS procedure collects larger samples and provides faster results than amniocentesis. Results may be received between one to seven days, but many doctors won't do this test for the purpose of paternity due to the risk of miscarriage. CVS the risk is 1 in 100, amnio the risk is 1 in 200 to 1 in 400. Miscarriages can occur because of infection in the uterus, the water breaks or labor is induced prematurely. A paternity test can be done soon after birth, with no fear of complications to the baby - the results may take two weeks to four months and costs $80 to several hundred dollars.
