DNA Test - San Angelo, Texas

San Angelo TX DNA Testing Locations

Types of DNA Tests at our San Angelo, Texas 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 San Angelo DNA testing technicians are trained to follow these guidelines so that the results will be legally admissible.

San Angelo, Texas - DNA Testing

Establishing paternity in San Angelo, TX

People from San Angelo, Texas, who are expecting a child outside of marriage can establish paternity through court or by signing an Acknowledgement of Paternity (AOP). The Acknowledgement of Paternity form is often signed at the hospital when the baby is born. However, an AOP should only be signed if both parents agree on paternity and have no doubts about who the biological father is. When signing AOP, parents must work with an AOP-certified entity that the Office of the Attorney General has trained.

If parents are unsure or disagree about paternity, they can go to court. In these cases, the judge often orders DNA testing. A DNA test is an easy method of determining whether the alleged father is the biological father. The judge can consider the results of the DNA test in the process of establishing paternity, but may also consider other factors. After paternity is legally established, parents can go through the court to establish child support, visitation, and custody if necessary.

San Angelo, Texas: Mistaken paternity

If an alleged father questions his relationship with a child, Texas law requires him to file a petition asking the court to terminate their relationship. Once the petition has been submitted, the Texas court will hold a pretrial hearing to decide whether he meets the legal requirements to proceed with the case. If so, a legal DNA test will be ordered for the alleged father and child.

If the genetic test proves the alleged father is not the biological father, the court can terminate their relationship. In this case, child support obligations may be relieved, but it is important to note that the man must still pay child support up to the date of termination. Sometimes, paternity cases can be very complex, and it is easier for the man to contact a lawyer to help him with the process.
