During an amniocentesis, a small sample of amniotic fluid is extracted from the amniotic sac surrounding the fetus using a thin needle. The sample is then tested in a laboratory to analyze the genetic material of the fetus and the alleged father. This test can determine paternity with a high degree of accuracy, usually greater than 99%.
A chorionic villus sampling (CVS) test involves taking a sample of the placental tissue that surrounds the developing fetus. This procedure is performed either through the cervix or through the abdomen using a needle. Like the amniocentesis test, the genetic material of the fetus and the alleged father is analyzed in a laboratory to determine paternity.
Both of these prenatal paternity tests have some potential risks and complications associated with them, including the risk of miscarriage, infection, or injury to the fetus or the mother. Therefore, they are typically only recommended when there is a medical need for them, such as for detecting genetic disorders. So, why wait? Schedule your CVS test with us to resolve your paternity disputes!
Benefits:
- CVS DNA test determines paternity of a developing fetus before birth
- Resolve uncertainty about the biological father’s identity
- Help make informed decisions about pregnancy and child’s future
- Assist in legal or medical reasons, such as inheritance or child custody cases
- Provide an opportunity for the father to bond with the developing fetus during pregnancy
- Reduce the emotional and financial cost of paternity testing after birth
- Early detection of genetic disorders or chromosomal abnormalities in the fetus
- Better preparation for the birth of a child with special medical needs.
CVS DNA Test While Pregnant
It is possible to take a DNA test while pregnant, but it’s important to consult with a medical professional first. A CVS test is one type of prenatal genetic test that can be performed to diagnose certain chromosomal abnormalities, genetic disorders, and other conditions in the fetus.
CVS vs Amniocentesis
Here are the differences between the two tests in bullet points:
CVS:
- Done in the first trimester (10-13 weeks)
- A small sample of the chorionic villus is taken from the placenta
- Can diagnose genetic disorders, such as Down syndrome, cystic fibrosis, and sickle cell disease
- Can also determine the sex of the fetus
- Slightly higher risk of miscarriage compared to amniocentesis
- Results are available within a few days
Amniocentesis:
- Done in the second trimester (15-20 weeks)
- A small amount of amniotic fluid is taken from around the fetus
- Can diagnose genetic disorders, such as Down syndrome, cystic fibrosis, and sickle cell disease
- Can also detect neural tube defects and some other abnormalities
- Lower risk of miscarriage compared to CVS
- Results are available within a few weeks
Which is better amniocentesis or CVS?
The choice between amniocentesis and CVS depends on factors such as timing, reason for testing, and patient preference.
