Although it is easiest to perform a DNA paternity test once a child is born, prenatal testing is available. In order to perform a prenatal paternity test, an invasive procedure is required to obtain a DNA sample from the developing fetus. Either a chorionic villus sampling (“CVS”) or an amniocentesis, performed by the mother’s OB/GYN, will provide the necessary DNA sample from the fetus. CVS can be performed early in pregnancy, usually between the tenth and twelfth weeks. Later in pregnancy, usually between the twelfth and twentieth weeks, an amniocentesis may be performed. However, neither procedure is considered standard, therefore, the mother must first consult with her physician to determine whether either procedure is even an option for her. If and when a prenatal sample is collected, the physician will submit that sample directly to the laboratory for testing. To test the alleged father and mother, only buccal swab samples would be necessary. Either a home DNA collection kit may be used if the test is only for private purposes, or an appointment at an authorized sample collection facility can be scheduled if the test is needed for legal purposes. Once all samples are collected and received, turnaround is generally within 2 weeks.
