DNA Test - New Haven, Connecticut

New Haven CT DNA Testing Locations

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

How to Establish Paternity in New Haven, CT

When a newborn is delivered to an unmarried New Haven couple, only the mother is granted parental rights over the child at the time of birth as per Connecticut law. Because the couple is not married, a paternity establishment is necessary to legally identify the biological father, allow him to obtain his paternal rights over the child, and place his credentials on the child's birth certificate.

According to the Connecticut Department of Public Health, New Haven parents may establish paternity by completing an Acknowledgment of Parentage. Both parents can sign this voluntary form on-site once the child is delivered or through a New Haven County Department of Social Services office location. Note that this process must only be completed if both parents have full confidence in a child's paternity or if DNA testing has already confirmed the father's identity.

Navigating a Difficult Paternity Establishment in New Haven, CT

Following the birth of a New Haven child, a Connecticut parent may encounter difficulty when asking the other party to agree to establish legal paternity. This unfortunate situation will also prevent a parent from seeking monthly child support services, as the state cannot legally identify the child's biological father to provide support without the legal establishment of paternity.

When one party refuses to establish paternity, a New Haven parent must file for court-ordered parentage. Filing a petition to establish parentage through a New Haven County Family Court allows a judge to mandate that the presumed father appears in court and completes DNA testing to confirm he is the father. If DNA tests confirm the petition, the courts will establish paternity and enable both parents to move forward with child support and other related childcare hearings.

Experts in New Haven, CT Say…

In addition to child support agreements, two New Haven parents may also need to settle upon a child custody agreement. After DNA testing has been used to determine the father, both parents may want to request the assistance of the New Haven Family Court to develop a custody agreement if they cannot agree upon one themselves.

According to New Haven Family Law Attorney Matthew Dolan, Connecticut courts use the child's best interest standard when ruling on child custody and support. This standard includes an assessment of the child's developmental needs, each parent's relationship with the child, and the child's age.
