DNA Testing Evanston IL

Evanston IL DNA Testing Locations

Types of DNA Tests at our Evanston IL clinics:

The most commonly ordered DNA test is a Paternity Test to conclusively establish whether or not a man is the biological father of a child.

Paternity Testing can be performed at our testing centers. DNA Testing can be done for other close family relationships, such as:

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 people being tested. 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 registering online and shipping the specimens to us.

Legally Admissible DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible DNA testing service. 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. In order for the results of a DNA test to hold up in court, for child support, or to change the name on a birth certificate, the test must be done at a clinic using strict chain of custody procedures. Our Evanston DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Evanston, Illinois - DNA Testing

DNA Test Proves Evanston Graduate was President Harding's Daughter

It was long rumored that President Warren G. Harding fathered a daughter with his mistress Nan Britton. The woman ignited a White House sex scandal when she published the best-selling book, The President's Daughter. However, historians have long questioned her tale—until DNA tests confirmed the truth just eight years ago.

Elizabeth Ann Blaesing, who attended high school in Evanston, was proven to be the child of Harding and Britton when their grandson took a genetic test that showed he was, in fact, their offspring. When asked about his grandparents' relationship, James Blaesing, 65, said, "You know what this is? It's a love story. It was true love, especially on her side, and I know he felt the same way."

Establishing Paternity in Evanston

According to the Evanston-based Mother's Rights Law Firm O. Long Law, LLC, there are several ways to establish a child's legal paternity in the state of Illinois. First, if the mother is married when the child is born, the law assumes her husband is the child's father. This is also true if the couple is separated but was married within 300 days of the child's birth.

When a child is born to parents who are not married, both parents can sign and file a Voluntary Acknowledgment of Paternity form any time before the child's 20th birthday. The office of Child Support Services can also submit an Administrative Paternity Order. This establishes paternity and allows for the establishment of a child support order at the same time. Finally, an interested party can petition the courts to issue an order of paternity. In most cases, the judge will require a DNA paternity test before ruling on the case.

Why is Establishing Paternity Important?

There are many important reasons to go through the process of establishing a child's legal paternity. Without it, a father has no rights to request visitation or custody and cannot legally have a say in parenting issues. Once paternity is established, a child can develop a relationship with his or her father, access the father's medical information, and receive financial and insurance support from both parents. The child can also receive an inheritance from the father and will have rights to Social Security, Veterans' and other benefits based on the father's record.
