McKinney TX DNA Testing Locations

Types of DNA Tests at our McKinney, Texas locations:

The most commonly ordered DNA test is a Paternity Test to conclusively establish whether or not a man is the biological father of a child.

Paternity Testing can be performed at our testing centers. DNA Testing can be done for other close family relationships, such as:

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 people being tested. 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 registering online and shipping the specimens to us.

McKinney, Texas - DNA Testing

Establishing paternity in McKinney, TX

Establishing paternity in McKinney, Texas, is one of the most crucial steps in the child support process. When parents are unmarried, they must establish paternity, unlike when they are married when the husband is automatically considered the legal father.

There are two options for establishing paternity in Texas. Parents can voluntarily sign an Acknowledgment of Paternity if they are sure of the biological father. They often get this option right after the baby is born at the hospital, or they can do it later. Another way to establish paternity is to go to court. This option is more common if the parents are unsure about who the biological father is or if one party does not cooperate. Based on the DNA results, the judge will likely ask the alleged father and the child to take a DNA test. A DNA test is usually done as a cheek swab, so it is safe, quick, easy, and painless.

DNA test reunited Texas mother and daughter

It took them 49 years to find a way back to each other. Mother and daughter reunited after almost five decades in Texas! Marcy was just 16 when she gave birth. She made a difficult choice and decided to put her baby up for adoption. She said that ever since she gave up on her baby, she never stopped looking for her.

Eventually, she took a DNA test which led to the match with her daughter. They reached out to each other and decided to meet in person. Marcy admitted she was nervous and excited and could not express her feelings since she had wanted to meet her daughter Elaine her whole life.

Once they met at the airport, Marcy gave Elaine her baby blanket, which she crocheted herself when she was pregnant. Both said they had so much to catch up on. They want to spend as much time together as possible to get to know each other better.
