Everything You've Always Wanted To Know About Fetal DNA Testing.

What is Fetal DNA Testing?

Fetal DNA testing is a process in which a woman records her pregnancy using a urine sample and a blood sample at various points in the pregnancy. The samples are then sent to a lab that analyzes the DNA of the fetus to determine if its father is the woman's husband or if it is from someone else. Afterward, a genetic test can be performed on fetal DNA to provide information about the child's genetic health and the likelihood of potential diseases.

How is Fetal DNA Testing Non-Invasive?

Non-invasive fetal DNA testing can be done in one of two ways:

• By extracting the DNA from the mother's blood on the day of the test
• By extracting the mother's blood and then following up with a blood sample from the baby tested.
• A third method is the use of amniocentesis, which is an invasive procedure that can be done at any time during pregnancy.

What Are the Risks of Having Fetal DNA Testing?

The risks of fetal DNA testing are similar to those of other prenatal tests. Some of the more common risks associated with this type of testing include:

• False-positive results
• False-negative results
• Injury to a fetus during a procedure
• Inability to find a match for a family member with a specific disease

Are Fetal DNA Tests 100% Accurate?

No, they are not. No test ever achieves a 100% DNA test rate, but top-notch laboratories can reach a 70-90% accuracy that makes their evaluations valid for consideration. Both positive and negative fetal DNA test results do not guarantee a child's genetic or chromosomal abnormality.
