DNA Test - Knoxville, Tennessee

Knoxville TN DNA Testing Locations

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

Knoxville, Tennessee - DNA Testing

Experts Say...

Peterson White, Knoxville's fathers' rights attorneys, advocates for the rights of Knoxville fathers. "The child's relationship with their father can be an important part of their development," the law firm explains, "Studies have shown that children may do better in school, in social situations, and at work, if their father was engaged throughout their childhood." The law firm explains how establishing paternity benefits the whole family. When the father becomes the legal father, he can have custody and visitation rights and access to the child's medical and school records. The child benefits by being financially supported by both parents, and having medical insurance, life insurance, and other available benefits, such as social security, inheritance, and veterans' benefits.

Establishing Paternity in Knoxville, TN

If a mother and father are married at the time of conception or within 300 hundred days of the child's birth, the law recognizes the husband as the child's legal father, and paternity is automatically established. However, Knoxville parents that are not married must establish paternity to give the child a legal father. The easiest way to establish paternity in Knoxville is to sign a Voluntary Acknowledgment of Paternity. This is a legal document that must be signed by a notary. It's a voluntary form, so both parents must agree to sign. However, if there is any question about who the biological father is, this form should not be signed, and parents should obtain a DNA test.

Proving Paternity for Child Custody Purposes in Knoxville, TN

When a mother and alleged father question the child's biological father, DNA testing can determine paternity. DNA testing should be done by a certified laboratory so that it is recognized by a court. If the parents still cannot agree to voluntarily establish paternity, they can go to court, and a judge will have the final say. Paternity must be established for the father to have rights to the child.
