Casper WY DNA Testing Locations

Types of DNA Tests at our Casper WY clinics:

Paternity Testing can conclusively establish whether or not a man is the biological father of a child.

Relationship Testing for other close family relationships can be performed at our testing centers. Our DNA testing services can confirm or deny biological relationships between grandparents, grandchildren, siblings, half-siblings, aunts, uncles, nieces and nephews:

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 alleged father and child or children. 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 ordering one of our testing kits online and shipping the specimens back to us.

Legal DNA Tests vs. “Peace of Mind” At-Home Tests

A Legal Paternity Test is a court admissible lab testing service performed at an AABB accredited laboratory. 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. A legal paternity DNA test will hold up in court for such matters as child support or to change the name on a birth certificate. This test must be performed using strict chain of custody procedures. Our Casper DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

Casper, Wyoming – DNA Testing

Establishing paternity in Casper, WY

In Casper, Wyoming, two primary options are available for unmarried parents looking to establish paternity. The first is a voluntary Affidavit of Parentage that legally identifies the man as the biological father and allows for his name to be added to the birth certificate. The second option is judicial establishment through court intervention. For women who are married at the time of a child’s birth, the husband is automatically considered the legal father, although this can be contested by signing a Denial of Paternity Affidavit.

In cases of disagreement between the mother and the alleged father or between the mother and her spouse, DNA testing serves as a definitive mechanism for establishing biological parentage. Health Street offers DNA testing services that are 99.9% accurate with a quick turnaround time, available at multiple walk-in clinics in Casper.

DNA test brings the family together in Wyoming

In Wyoming, a man initially hesitant about DNA testing was persuaded by his mother to look into his ancestry. Upon receiving the results, he discovered an unexpected family member—an uncle he had never known about. The man’s father had been adopted and had chosen not to search for his biological parents out of respect for his adoptive family. No one knew that another sibling existed.

Debating whether to inform his father, the man eventually decided to share. This led to a family meeting in Utah where they found yet another brother who also came from Wyoming. Upon digging further, they realized all of them shared the same biological mother but had different fathers. They even found a sister, although her details are still unknown.

Why Choose Health Street for DNA Testing

For those in need of reliable, quick, and accurate DNA testing, Health Street is your trusted resource. Whether you’re looking to establish paternity for legal reasons or seeking to confirm another biological relationship, Health Street can help.
