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.

Facts about DNA Testing in McAllen TX

Many Bi-National Children Grow Up in McAllen

Many residents of McAllen grow up with family on both sides of the border. Being bilingual is common, and many residents meet, date, and marry people who have a different nationality, but work in the same area, shop in the same stores, and go to the same churches and other houses of worship.

When children are born to parents who are undocumented, or from two different sides of the border, it can make issues of paternity and child support complex. Texas RioGrande Legal Aid was established in 1970, and they’ve recently formed a working group to deal with bi-national family issues, including family violence. They can also offer representation and assistance in enforcing court orders in Mexico, and other bi-national custody issues.

Navigating the Complexities of International Co-Parenting

In Texas, paternity is typically established by either legal presumption (when the parents are married), by filing an Acknowledgement of Paternity form, or through a court order. This may seem simple, but in Texas, issues like the mother being married to another man within 300 days of the baby’s birth can complicate otherwise straightforward questions about parentage.

Even without dealing with border issues, co-parenting can be complex. That’s why many families in McAllen choose to either voluntarily undergo genetic testing or file a motion for a judge to order genetic testing of the child and potential father. Local McAllen lawyer and binational law expert Robert C. Sheline suggests that “one should err on the side of caution and require DNA paternity testing,” as there are many different factors that could be influenced by this decision, including the paternity of and child support for other children.
