DNA & Paternity Testing

GSI-imageGrand Slam Investigations offers DNA testing and paternity tests that are fast, easy-to-use, completely confidential and greater than 99.99% accurate.


Our DNA testing and paternity test partner provides paternity tests for thousands of customers, and is recognized as a world leader in the science of DNA testing. Regardless of your situation, we have a DNA test to help you find the truth.


Legal DNA paternity test results are admissible in most courts of law. Although our laboratory adheres to the most stringent standards for testing, some states may differ in their requirements. Unlike our home paternity test, the Legal DNA Paternity Test tracks your DNA samples from the time they’re collected by one of our trained specialists until the time they arrive in our DNA testing laboratory, which ensures they’re admissible as evidence in a courtroom.


We offer many different types of DNA tests including Home Paternity Tests, Full Sibling DNA Tests, Half Sibling DNA tests, Prenatal DNA Paternity Tests, and more.
