Paternity Testing Long Island

Paternity Testing

A paternity test essentially uses your DNA to establish a biological connection with your father. If you’re not sure who the father of your child is, or you are adopted and want to discover about your parents, a paternity test is the easiest solution. 


A DNA paternity test works by comparing the child’s DNA with the expected father’s DNA. If the child’s DNA resembles the father’s DNA it’s a match! The Y chromosome passes practically unaltered from father to child.  This not only allows for the identification of the child’s father but is also used to trace down your paternal line. 

Legal DNA paternity testing is essentially required for:

  • Child custody and support

  • Adoption

  • Immigration

  • Will

  • Proving  paternity in a courtroom

  • Changing the name on a birth certificate

  • Other legal reasons


At Long Island DNA Testing, we offer:

  • Legal DNA Paternity Test: Your sample will be collected and processed at our lab. All results are private and confidential and provided only to legal authorities upon court order. Your information is safe with us!

  • Home DNA Paternity Test: One of our DNA collectors can come to your house to perform your DNA test, all in the comfort of your own home.
