DNA Testing Marietta, Georgia

Marietta GA DNA Testing Locations

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

Facts about DNA Testing in Marietta GA

Georgia Requires Mandatory Paternity Testing in Disputed Child Support Cases

For child support cases in Marietta, Georgia (part of Cobb County), genetic testing may be required. In 2015, Georgia required mandatory paternity testing for all new child support cases in which paternity is not already legally established. Instead of taking a DNA test, parents can establish paternity by:

Being legally married at the time of the child’s birth
Signing a Voluntary Paternity Acknowledgment Form
Receiving a court order like a divorce decree or separation agreement

According to the law, fathers involved in cases in which the paternity of a child has not been confirmed in one of these three methods will be required to take a paternity test. The cost of the test is the responsibility of the father if paternity is determined or the mother if paternity is not found.

Georgia Man Abandoned as Baby Discovers Biological Family with Help of Marietta Genealogist

A Georgia resident who was abandoned as a baby finally learned about his hidden past with the help of Marietta local Gerri Berger. Berger is a Genetic Genealogist, specializing in helping adoptees and others with unknown parentage discover their biological family’s history. Berger helped Richard Cole, the infamous baby left by an unknown woman in an Atlanta hotel in 1944, find answers about the long-lost parents he’d wondered about for 75 years.

Berger used a combination of DNA test results and genealogical sleuthing to track down a half-sibling of Cole’s, Pamela Williams. When Cole and Williams finally talked and eventually met, they said the similarities between Cole and the Williams family were striking. Williams and her other siblings have since embraced Cole as a part of their family.

DNA Test Proves Two KSU Students in Marietta Have More in Common than Just Their Major

Two Kennesaw State University (KSU) students in Marietta, GA recently got a surprising answer to a riddle that had plagued them both for decades. Kieron Christian Graham was put up for adoption when he was three months old. His older brother Vincent Ghant, then nine years old, was told Graham had gone to stay with grandparents and that he’d come back soon. In reality, Graham and Ghant’s mother was a single mother and full-time nurse who put Graham up for adoption after becoming overwhelmed with her many responsibilities.

In 2017, Graham took an at-home DNA test that immediately linked him with Ghant. Incredibly, both men were studying political science at KSU with a specialization in legal studies. They are both avid Atlanta Falcons fans and even held the same positions on their high school football teams. Now, they are happy to be a part of each other’s lives.
