DNA Test - Joliet, Illinois

Joliet IL DNA Testing Locations

Types of DNA Tests at our Joliet, Illinois locations:

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 Joliet DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Joliet, Illinois - DNA Testing

Experts Say...

"When the parents of a child are unmarried, establishing paternity is a vital legal step to ensure the child receives the financial support he/she is entitled to, and father's rights are protected," says The Law Offices of Tedone & Morton, P.C. of Joliet, IL, "In Illinois, law paternity is called parentage."

The Law Office of Dawn R. Underhill, serving Joliet and Will County, says, "At the forefront of every paternity case is a child—a child who, regardless of age, deserves to grow up in an environment where he or she knows, is loved by and is supported by both parents."

Proving Paternity for Child Custody Purposes in Joliet, IL

There are two ways to establish parentage in Joliet. Parentage can be established voluntarily if both parents agree to sign a voluntary Acknowledgement of Parentage form, and signing the form avoids the need to go to court. If either parent refuses to sign the voluntary form or if there is any question about the biological father, parentage can be established through DNA testing. An alleged father can agree to DNA testing willingly, or he and the mother can go to court for parentage establishment, and the court can order the DNA testing to prove paternity.

The Importance of Establishing Paternity

In Joliet, paternity must be established for the court to issue certain rights, including child support for the mother and custody or visitation time for the father. Paternity establishment benefits the child by allowing access to medical benefits, social security or veteran's benefits, pensions, inheritance, and medical DNA records from both sides of the family.

Joliet residents needing help with establishing paternity can call or visit the regional location of the Illinois Department of Healthcare and Family Services, located at 16 West Cass Street, 4th Floor, Joliet, IL 60432.
