DNA Test - Nashua, New Hampshire

Nashua NH DNA Testing Locations

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

Nashua, New Hampshire - DNA Testing

Experts Say...

The Law Office of Mike J. Demers in Nashua, NH, says, "The first step that must be done to pursue parental rights when you are not married to the other parent is to establish paternity. Without first establishing paternity, a father can't pursue custody or visitation of any sort." The law office explains some of the parental rights that come from establishing paternity. These rights include deciding where the child will live, religious teachings, making educational decisions, visitation, deciding insurance and medical needs, and receiving or contributing to expenses related to raising a child.

Establishing Paternity in Nashua, NH

In Nashua, parents that have a child out of wedlock should establish paternity as soon as they can so that the child has a legal father. Establishing paternity provides numerous benefits to the child and both parents, ensuring child support and access to benefits, including inheritance, medical benefits, and disability benefits; access to both families' medical information, a sense of identity for the child, and a chance to develop relationships with both parents.

Nashua parents can establish paternity by getting married, although marriage is not required for paternity. Parents can also establish paternity voluntarily by signing an Affidavit of Parentage. If the mother and the alleged father cannot agree to sign this form, they can establish paternity in court.

Proving Paternity for Child Custody Purposes in Nashua, NH

In Nashua, if parents establish paternity in court, the court will order DNA testing to determine paternity. If DNA testing determines the man is the child's biological father, the parents can sign an Affidavit of Parentage, or the court will proceed with the paternity process. Once paternity is officially established, the father's name can be added to the birth certificate. If the DNA test determines the man is not the child's father, the mother can file a new application naming another possible father.
