DNA Test - Laredo, Texas

Laredo TX DNA Testing Locations

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

Laredo, TX - DNA Testing

Establishing paternity in Laredo, TX

Birth parents who are unmarried and want to establish paternity can voluntarily sign an Acknowledgment of Paternity (AOP). Both parents must work with AOP-certified entities to complete and file it. If either party is unsure of paternity, DNA testing may be desired before signing the AOP.

When the mother and the father disagree about paternity, the Office of the Attorney General may file a petition asking the court to establish paternity. In this case, the court often asks the alleged father to take a paternity DNA test so they can determine whether he is the father of the child or not.

The DNA test is pretty simple. Usually, it is a simple cheek swab test done at a certified clinic. DNA tests from a certified lab can determine the biological father with about 99 percent accuracy.

Two sisters reunited thanks to a DNA test

Elia and Joi were both born in China. Since China had a one-child policy, they were also both adopted by parents in the USA. As adults, they wanted to learn more about their heritage, so they took DNA tests. They did not expect to find out they had a sister.

Joi took more DNA tests in the past, but they never led to anything until Elia also took hers. Elia was 21 years old, and Joi was just one year older. Having found each other as young adults, they are pleased to realize how many opportunities they have left to share. They can still see each other graduate, get married, and experience many big moments in their lives together.

They are both delighted that they found each other! Today, they encourage anyone who wants to find their biological family to never stop looking.
