Some expectant mothers want or need to establish the paternity of their child before the baby is born. DNA Diagnostics Center offers prenatal paternity testing for these mothers. Because this type of paternity testing involves taking a sample of the unborn baby’s DNA from inside the mother’s womb, there are some risks to the developing fetus and other things to consider in deciding whether a prenatal paternity test is right for you.

The baby’s gestational age – how far along the pregnancy has progressed – is the first thing an expectant mother must consider. Prenatal paternity testing can only be performed when the expectant mother is between 10 to 24 weeks pregnant. If the pregnancy is in the 10th to 13th week, chorionic villi sampling (CVS) is the sample collection procedure that is performed. However, if the expectant mother is in her 14th to 24th week of pregnancy, amniocentesis is the procedure that will be used.

In each of these procedures, fetal DNA is collected by removing extraneous cells—those that the fetus have shed into the surrounding fluid (amniocentesis), or from cells from the placenta (CVS). These cells are taken from the mother using a long, thin needle inserted through the cervix or the abdomen, depending on fetal size and position. The fetal DNA is then compared with the mother’s and alleged father's DNA to determine paternity. These procedures are performed by an OB-GYN. DNA Diagnostics Center partners with a network of OB-GYNs across the United States and can make arrangements for patients who do not already have an OB-GYN for their prenatal care.

Recently, studies have indicated the possibility that non-invasive methods can be used to determine paternity. Several methods have been studied, but the most popular centers on the notion that fetal DNA seeps into the expectant mother’s bloodstream and therefore would be present in a sample of the mother’s blood. These studies indicate that if fetal DNA can be isolated in the mother’s blood, this method could be used to determine paternity without the risks associated with CVS or amniocentesis.

However, such non-invasive studies are at an early stage of development and need refining before they become an industry-accepted, valid and reliable form of prenatal paternity testing. Because the non-invasive prenatal sampling procedure is not yet an established method, AABB-accredited laboratories generally do not offer this type of prenatal DNA testing. AABB accreditation is required for legally defensible test results and is the gold standard in accreditation in the DNA testing industry. As an AABB-accredited laboratory, DNA Diagnostics Center does not yet perform or recommend any form of non-invasive prenatal paternity testing.
