While invasive methods carry substantial risk, modern developments in medicine make new forms of testing possible. Whether you are interested in DNA testing services for legal reasons or peace of mind, explore the guide below for more information about your options.

Guide to DNA Testing Options Before Birth 

Testing Methods Saint Louis DNA Testing

The available methods of prenatal DNA testing include amniocentesis, chorionic villus sampling, and a new non-invasive option which includes a maternal blood test. Amniocentesis, which is often used to diagnose chromosomal abnormalities, can also determine a baby's father. During amniocentesis, a doctor inserts a small needle into a mother's abdomen to draw amniotic fluid from the uterus.

Chorionic villus sampling, also known as CVS, is another option. It requires a fluid sample drawn from the mother’s uterus. Physicians obtain the DNA through the abdomen or vagina.

The final available DNA sample method is taken through blood drawn from the mother’s arm. Once the child's DNA is separated from blood plasma, it is compared to the potential father's results. Testing options for the male include blood, hair, and cheek swab. Mothers and prospective fathers can also choose to wait until after birth to complete a non-invasive test.

Sampling Risks

The risks of obtaining a prenatal DNA sample vary depending on the chosen approach. Since both amniocentesis and CVS are invasive procedures, women who have them are at a higher risk for miscarriage. Chorionic villus sampling can also result in birth defects. Due to these dangers, non-invasive blood samples are the safest and most efficient testing option. These analyses also cost less than the other methods and can be completed in minutes.
