Paternity testing (trio) DNA samples are obtained from inside of the mouth of the mother, one child, and one alleged father with a cotton swab.

Paternity testing (single parent) DNA samples are obtained from inside of the mouth of one child and one alleged father with a cotton swab. The collection of the mother's sample is not absolutely necessary for DNA paternity testing; however, the mother's sample helps to identify in the child those genes that came from the mother and eliminate them from consideration in a paternity test. The laboratory can perform a highly accurate DNA paternity test without the mother's sample by performing additional DNA analysis (called single parent-child DNA paternity test).

Results when the man is NOT the father.
Our results for paternity proves conclusively that the tested man is NOT the biological father of the child. In such cases, the tested man's genes do not match the child's genes on at least three different genes. The probability of paternity is 0%, and we are 100% certain that he is NOT the child's biological father.

Results when the man IS the father. Our average probability of paternity is greater than 99.99999%. We guarantee greater than 99.9% probability of paternity in all tests where the child and alleged father are tested.*

*In rare cases, genetic mutations are identified during DNA testing. Our laboratory does not guarantee results with greater than 99.9% probability incases where these rare genetic mutations are identified. In cases with genetic mutations, additional charges will apply for extended DNA testing. .
