DNA Test - Iowa City, Iowa

Iowa City IA DNA Testing Locations

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

Establishing Paternity in Iowa City, IA

Paternity means fatherhood. When a mother and a father are married when the child is born, the husband is automatically the child's legal father. However, in Iowa City, if a child is born out of wedlock, the biological father isn't the child's legal father until the parents establish paternity. Iowa City parents can establish paternity through marriage, by signing a paternity affidavit, or in court. Parents can complete a paternity affidavit at the hospital when the child is born, at the Bureau of Health Statistics, the Child Support Recovery Unit, or at the Johnson County Registrar's Office.

Proving Paternity For Child Custody Purposes in Iowa City, IA

Iowa City parents should not sign a paternity affidavit if they question paternity until DNA test results determine the father. If either parent questions or doubts paternity, they can request DNA testing to determine the child's biological father. If establishing paternity in court, the judge may order DNA testing. A DNA test can exclude a man as the father or determine the likelihood that he's the child's biological father. In Iowa City, if a DNA test shows a 95% probability or higher that he's the child's father, he's presumed the father.

The Importance of Establishing Paternity in Iowa City, IA

Establishing paternity provides multiple benefits for the mother, father, and child. Children that have two legal parents benefit by developing relationships with their mother and father and get a sense of identity and belonging. Establishing paternity allows the child to gain access to medical records from both sides of the family. In Iowa City, establishing paternity also gives children access to financial assistance, medical benefits, and other benefits, like social security, veterans' benefits, inheritance, and life insurance.
