Our fee for a standard, chain-of-custody (legally-admissible) paternity test, involving one possible father and one child, is $395. Testing of the mother and sample collection at over 1,000 U.S. locations is provided at no additional charge. Also, because paternity testing is a service, no tax is added to the testing fee. Other types of DNA relationship tests may be more or less expensive depending on the nature and complexity of the tests and services provided.
