DNA Test - Washington, District of Columbia

Washington DC DNA Testing Locations

Types of DNA Tests at our Washington, District of Columbia clinics:

Paternity Testing can conclusively establish whether or not a man is the biological father of a child.

Relationship Testing for other close family relationships can be performed at our testing centers. Our DNA testing services can confirm or deny biological relationships between grandparents, grandchildren, siblings, half-siblings, aunts, uncles, nieces and nephews:

Grandparent DNA Test (if the father is not available for testing)
Sibling DNA Test (possible brothers, sisters, or half-siblings)
Avuncular DNA Test (aunt/uncle and niece/nephew)

Specimens we can test for DNA

The easiest and most reliable way to obtain a DNA sample for paternity testing is to swab the inner cheeks of the alleged father and child or children. These skin cells are known as buccal cells, and they rub off easily onto cotton swabs and remain in place for analysis by our laboratory.

Other specimen samples, such as hair follicles, fingernails, and garments that might contain someone's DNA, can also be tested. An Alternative Specimen DNA Test is done by ordering one of our testing kits online and shipping the specimens back to us.

Legal DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible lab testing service performed at an AABB accredited laboratory. Accurate results for DNA paternity testing with 99.99% confidence or greater take about a week.

When deciding which type of DNA test is right for you, consider first what you might do with the results. A legal paternity DNA test will hold up in court for such matters as child support or to change the name on a birth certificate. This test must be performed using strict chain of custody procedures. Our Washington DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Washington, D.C. - DNA test

Establishing paternity in Washington, D.C.

In Washington D.C., when a child is born to partners who are not married or in a registered domestic partnership, there is no automatic legal relationship between them, and parents should establish the parentage.

There are two legal ways of establishing parentage, either by a court order or by signing a Voluntary Acknowledgment of Paternity (AOP). If the parents agree, they can sign the AOP and do not need to go to court to establish the parentage. Signing the AOP will allow the father's name to be placed on the birth certificate.

If the parents do not agree to sign the AOP, they can file a petition through The Child Support office. Usually, a court hearing will ensue, and the court often orders DNA testing. If the DNA test proves the man is the father, paternity will be established.

Benefits of establishing paternity in Washington, D.C.

There are multiple benefits connected to establishing paternity:

There will be a legal bond between father and child
Children who know both of their parents often perform better in school and are also more likely to avoid drugs and criminal behavior
The establishment of parentage is necessary for child support
There may be insurance benefits or possible inheritance
Children will know their medical history from both parents

Washington, D.C.: Challenging paternity

When a child is born to unwed parents in the District of Columbia, the parents can decide to sign an AOP without performing any DNA testing. However, if someone else questions the child's paternity, there will be no medical evidence of the biological father.

In this case, the court will likely order a DNA test to determine who the birth father is. After the court receives the DNA test results, paternity can be established, and the man who proves to be the father will have legal responsibilities toward the child.
