Paternity Testing on Long Island, NY

DNA Test Between a Father and Child

The basis of paternity is the inheritance of DNA from both the father and the mother. This marvelous phenomenon has allowed us to advance genetic biology, and one of the marvels of this technology is the development of Paternity testing.

A paternity test is performed to confirm the biological relationship between a child and his alleged father.  Throughout the history of medicine, there have been and still exist various methods for a paternity test, including blood tests and DNA testing. However, with the advancement in medical technology, DNA testing is the most accurate paternity test with an accuracy of 99.9%. 

Paternity Testing can be required in several cases, including immigration, child custody, adoption, child support, will, and other lawful reasons. The sample is collected by rubbing a cotton swab on the inside of your cheeks. It is a simple, effective, and painless procedure where body fluids specifically saliva, is used. The DNA in the saliva of the child and the alleged father is tested, and the results show whether the DNA matches.
