DNA Testing College Park MD

College Park MD DNA Testing Locations

Types of DNA Tests at our College Park MD 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 College Park DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Facts about DNA Testing in College Park MD

College Park Professor Uses Research and DNA Tests to Explain Trends in American Families

In 2018, a College Park professor published a thought-provoking research paper entitled "The Coming Divorce Decline." That sociology professor, Philip Cohen from the University of Maryland, College Park, is an expert on family dynamics and has published two books that dive deeply into the question of what is family in today's America. While Cohen spends a great deal of his time doing traditional genealogical research, DNA testing databases have come to play a significant role in his research.

Through a combination of both types of research, researchers across the country have begun piecing together a national family tree database to answer some age-old questions. Cohen says of the project: "It's very impressive as a data collection and harmonization effort, and of course they have only scratched the surface of what it might have to offer."

Family Law Attorneys Help College Park Residents Use DNA Tests in Court

Maryland residents may be interested in DNA testing to help settle custody disputes, certify child support claims and much more. Specialized law professionals can help College Park residents understand what type of DNA test they need and how to use it in court.

Local attorney Lee Meriwether thinks it's important to think about paternity issues early, noting, "What goes on when you wait? When you sit on your rights? You're getting yourself in a position where you might not really be able to legitimate your child." Matrimonial attorneys can also help guide you through the difficult process of settling child custody issues.
