DNA Test - League City, Texas

League City TX DNA Testing Locations

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

League City, Texas - DNA Testing

Using DNA Testing to Establish Paternity in League City, TX

When two unmarried parents have a child in the state of Texas, the biological father will not possess legal rights until paternity is properly established. Establishing paternity is extremely important, as it not only provides unmarried League City fathers with parental rights but also supports the well-being of a child through benefits like health insurance and inheritance from both parents.

In certain instances of establishing paternity, a parent may have uncertainty about the identity of the biological father. If there is not 100% confidence in the presumed paternity, it's essential to first seek DNA testing services before establishing paternity to avoid any later legal complications in the state of Texas. The use of DNA testing enables both parents to more effectively establish paternity as well as legal orders such as custody or child support agreements.

Navigating Mistaken Paternity in League City, TX

In instances where League City parents move forward with establishing paternity without first using DNA testing services, they may later learn that the presumed father is actually not the biological father of the child. Fortunately, Texas Family Code allows the courts to terminate a parent-child relationship in the event of mistaken paternity.

To prove mistaken paternity in League City, a parent must file a petition with Galveston County Family Court to remove any existing paternity establishment and/or child support agreement. The courts will request the proof of DNA testing results to accurately verify the paternity claim, after which a judge can terminate the parent-child relationship as well as child support obligations.

Experts in League City, TX Say…

As previously mentioned, when two unmarried League City parents have a child, the two will need to establish paternity themselves. However, there are certain circumstances where paternity can be automatically established under Texas paternity law. According to League City paternity attorney Daniel Bacalis, paternity is automatically established when a man is legally married to the mother at the time of their child's birth or when two parents had been previously married and the child was born within the first 300 days after their divorce.
