DNA Test - Thornton, Colorado

Thornton CO DNA Testing Locations

Types of DNA Tests at our Thornton, Colorado 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 Thornton DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Thornton, Colorado - DNA Testing

Establishing paternity in Thornton, Colorado

If parents were married when the baby was born, or the child was born 300 days after a divorce, the husband is considered the legal father. If the husband questions it, he and the alleged father can be tested for paternity, or the alleged father can admit paternity even without a DNA test and become a legal father.

If the Coloradoan parents are unmarried, there are two ways to establish paternity in Colorado. The child's father can sign a voluntary affidavit that states he is the father, or the court can decide. Involving the court usually results in DNA testing to determine whether the man is the biological father or not. Many people choose to go to court if either parent is unsure about who the biological father is.

Benefits of Establishing Paternity in Colorado

It's important to establish legal paternity even if a child's parents have a good relationship. According to Colorado's Pearman Law Firm, establishing legal paternity allows the courts to rule on important topics like visitation, custody, and child support. It also allows the child to receive benefits such as insurance coverage and veterans and/or Social Security benefits payable to dependents.

A man who has raised a child as his own may want to establish legal paternity, even if he's not the child's biological father. This gives him equal rights to have a say when it comes to making decisions regarding the child's healthcare, education, religion, and other important matters.

Tips for Handling Paternity Disputes

In some cases, the paternity of a child is disputed. When this happens, it's often brought before the courts. According to Team JLaw, an attorney group that services Thornton and the surrounding area, a presumption of paternity can be rebutted when there is clear and convincing evidence. When paternity is in question, a DNA test can help resolve the issue. A "Motion for Genetic Testing" can be filed by a representative for the child, the mother, the presumed father, or certain state agencies.

DNA test reunited Colorado woman with her mother

Sarah from Colorado reunited with her mother, who gave her up for adoption when she was just fourteen months old. Her mom is from South Korea, and back in the 60s, she was hoping Sarah would have a better life than what she could have given her if she had kept her.

Sarah was adopted with her half-brother by a family in New Hampshire. They both got a locket with their and their mother's pictures inside. After 50 years, the search for the mother was finally successful. Sarah took a DNA test, and soon after, she matched with her mother and met her with her two children.

Sarah was delighted and grateful for her mother, who selflessly gave her up to give her a better life. Now, they are building up their relationship and reconnecting as a family.
