A legal DNA Paternity Test gives a result that may be used for legal purposes. Participants must have a valid form of identification. Thumb prints and photographs will be taken during the specimen collection process. This test may be used for divorce cases or other legal purposes. Please contact the laboratory before purchase if you need a test for US Immigration. It is not necessary to test the mother, but the test may take longer and it may be necessary to perform additional testing if she is not included in the test. Be advised that $100 of the payment is set aside as a deposit and is non-refundable in the event that the test is canceled.
