Islip NY DNA Testing Locations

Types of DNA Tests at our Islip, New York 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)
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 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.

Legally Admissible DNA Tests vs. "Peace of Mind" At-Home Tests

A Legal Paternity Test is a court admissible DNA testing service. 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. In order for the results of a DNA test to hold up in court, for child support, or to change the name on a birth certificate, the test must be done at a clinic using strict chain of custody procedures. Our Islip DNA testing technicians are trained to follow guidelines that ensure that the results can be used for legal purposes.

Proving Paternity for Child Custody Purposes in Islip, NY

In Islip, NY, if you agree you're the child's father, you can establish paternity by signing a voluntary affidavit. By signing the affidavit, you and the mother agree that you're the father and there are no other possible fathers to the child. If you establish paternity by signing the voluntary affidavit, you do not need to go to court to establish paternity.

If you refuse to sign the affidavit, you'll need to establish paternity in family court. You'll also go to court if there is more than one possible father, or the mother was married to someone else when the child was conceived or born. If you believe you're the father, you have the right to begin a court case.

If there's any question, or you want to be sure that you're the father, you can request DNA testing to prove paternity. DNA samples are taken from you, the mother, and the child, and show nearly 100 percent probability that you're the father. Once DNA testing proves paternity, the court will order an Order of Filiation to establish paternity. If you still deny paternity after DNA testing, you will go to court for a trial.

"A question of paternity may be raised in divorce when child support and custody issues are raised," he said. "The focus of a paternity case is to determine the identity of a child's father.
