Lewisville TX DNA Testing Locations

Types of DNA Tests at our Lewisville, 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)

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.

Lewisville, Texas - DNA Testing

Experts Say...

Steele Law, P.C., paternity lawyers in Lewisville, TX, explains why it's important for unmarried parents to establish paternity. "It is important and necessary for children to receive love and support from both of their parents. There are times, however, when Texas fathers are not allowed to see their children or when there is a disagreement regarding parentage." According to the law firm, unmarried fathers must establish paternity to obtain parental rights. "An alleged father who wishes to have paternal rights will have to secure acknowledgment of paternity or file a lawsuit to prove fatherhood."

Proving Paternity for Child Custody Purposes in Lewisville, TX

Establishing paternity means giving the child a legal father. In Lewisville, TX unmarried parents must establish paternity for the father to have parental rights and responsibilities. Paternity can be established if both parents agree to sign an Acknowledgment of Paternity (AOP) form. If either the mother or the alleged father is unsure of or denies paternity, DNA testing should be used to prove paternity, and an AOP form should not be signed until paternity is determined. DNA tests require cheek swab samples and can determine paternity with 99 percent accuracy. If two parents cannot agree to sign a voluntary paternity form, paternity can be established in court, and the court may order DNA testing.

The Importance of Establishing Paternity in Lewisville, TX

By establishing paternity, Lewisville fathers obtain parental rights and responsibilities, like visitation and custody rights and financial responsibilities. Children with legal fathers also have rights to certain benefits from both parents, such as medical benefits, life insurance, social security, veteran's benefits, or other benefits available from either parent. Another benefit of establishing paternity is that it allows the child to have relationships with both parents and the ability to access medical records from both families to see if there are any genetic diseases or traits that will affect the child.
