DNA Test – Greenwich, Connecticut

Greenwich CT DNA Testing Locations

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

Greenwich CT DNA Information

Establishing Paternity in Greenwich

When a child is born to unmarried parents in Connecticut, the parents must take steps to establish legal paternity. According to Heidi E. Opinsky, an attorney serving Greenwich and the surrounding area, there are two primary ways for an unmarried couple to establish paternity. The first, and easiest, is for both parents to sign and file an “Acknowledgment of Paternity” form.

If the couple doesn’t agree about the identity of the child’s biological father, then one party will need to file a petition with the courts, asking them to schedule a paternity hearing. In this case, the courts will require DNA testing before making a ruling.

Reasons to Establish Legal Fatherhood

Establishing paternity is more than a legal formality. In fact, Fairfield County paternity lawyers Schoonmaker, George, Colin, Blomberg, Bryniczka, & Welsh point out many important reasons to establish paternity. This includes encouraging a healthy parent-child relationship, giving the child rights to the father’s healthcare and other benefits, and terminating the other parent’s right to put the child up for adoption. In addition, paternity must be established before courts can rule on important matters like custody, visitation, and child support.

Contesting Paternity in Connecticut

What happens if a man is told he’s a child’s biological father, but he isn’t sure? According to attorney Maya Murphy, who serves Greenwich and the surrounding area, there are some legal ways to deal with this. If the parents have signed an acknowledgment of paternity form, either party has 60 days to rescind it. After 60 days, the matter must go to court.

If a paternity case is brought to court, a DNA test that shows a man is a child’s biological father is admissible without authentication. However, it is possible to make an objection to the test, it it’s done within the 20 days prior to the court hearing.
