DNA Test - McAllen, Texas

McAllen TX DNA Testing Locations

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

Importance of Establishing Paternity in McAllen, TX

McAllen fathers that aren't married to their child's mother do not have legal rights to their child until paternity is established. Establishing paternity benefits the child, mother, and father. Paternity means fatherhood, and establishing paternity allows the biological father to have parental rights to the child.

When paternity is established, the child benefits by knowing both sides of the family and establishing bonds with both parents, providing the child with a sense of identity. The mother and child both benefit by obtaining financial and parental support from the father. When paternity is established, the child also obtains rights to any available inheritance, medical benefits, veteran's benefits, social security, and other benefits the father has to offer.

Experts Say...

"When a child is born to a couple that is not married, the name of the birth mother is the only name that is automatically added to the birth certificate," says the family law attorneys of Scott M. Brown and Associates, serving McAllen, TX. "To be legally considered a parent to a child, one or both of the parents will need to file a case to establish paternity."

Proving Paternity for Child Custody Purposes in McAllen, TX

Unmarried parents in McAllen, TX must establish paternity for the child to have a legal father. If both parents agree about who the child's biological father is, they can establish paternity voluntarily by signing an Acknowledgment of Paternity form. If a mother and the alleged father do not agree or have doubts about the child's biological father, a court order will establish paternity. If the father's identity is questionable, the mother and the alleged father should obtain a DNA test to prove paternity. In this case, paternity should not be established voluntarily until the biological father has been determined. DNA testing must be conducted at a certified laboratory, and home DNA test kits are not admissible in court.
