DNA Test - Sioux City, Iowa

Sioux City IA DNA Testing Locations

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

Sioux City, Iowa - DNA Testing

Establishing paternity in Sioux City, Iowa

When married parents have a baby in Sioux City, the husband is automatically considered to be the legal father. However, unwed parents in Sioux City must establish paternity by signing a paternity affidavit or going to court. If the parents have no doubts about paternity and want to sign the affidavit, they can do so after the child is born at the hospital or later. Once the document is signed, it is necessary to file it with the Bureau of Health Statistics. After that, the father's name will be added to the birth certificate, and he will have the same rights and responsibilities as the mother.

Another way of establishing paternity is via court. Usually, people opt for this when they are still determining who is the birth father. The court often asks the alleged father and the child to take a DNA test, so there is proof of a father-child relationship. If the tests return positive, the judge can establish paternity and custody, child support, and visitation.

Change in Iowa's law reunited father with daughter he did not know was alive

Tom and Barb were dating, and he wanted to marry her. A few months after he proposed, she told him she was pregnant. A few weeks before the birth, they decided to give the child up for adoption because they were so young, but once the baby was born, they were told she was dead. It was tough because they kept her pregnancy secret and could not share their loss. But she was not dead; she was actually adopted by another family who named her Cheryl.

Tom and Barb stayed together and had two more children. When Cheryl grew up, she married, and although her parents did not tell her she was adopted, she always knew. Her husband was also adopted, so when the law in Iowa changed, and adoptees could see their original birth certificates, they could not wait to find out who their parents were. She contacted her father, but he did not believe her and ignored all her messages. Eventually, she met her father and siblings. Her mother had already passed. Once they met, there were no more secrets, just many happy memories to share and more to create.
