  • A paternity test is a scientific test that compares the DNA of a child to the DNA of the mother and alleged father to determine if the tested man could be the biological father.

  • Preferably the mother of the child, the child, and the alleged father should be tested. However, testing is possible without the mother’s sample. In certain circumstances, when the alleged father is unavailable or deceased, it is also possible to conduct a test using stored samples (see Deceased Sample Testing section) from the alleged father or samples from his biological relatives.

  • It is possible to conduct a DNA paternity test without a sample from the child’s biological mother; however, it is preferred that the mother also provide a specimen.  Without the mother, the power of the testing is significantly reduced. Testing the mother provides the highest level of accuracy and is an important quality control component.

  • The samples for a legal DNA paternity test are collected by one of our 900 company-operated US locations or more than 10,000 contracted specimen collection sites globally. The samples for an at-home DNA collection are collected by the parties themselves in a non-clinical setting (usually at home).

  • LabCorp has more than 900 company-operated locations in the US and we have contracts with more than 10,000 collection sites globally. Please use our Collection Site Locator to find a collection site near you. 

  • No, parties can provide their samples at different times and in different cities, states, or countries. LabCorp has a large specimen collection network, making it more convenient for all parties to submit samples.

  • Buccal swabs and blood samples provide results with the same degree of accuracy.  Since buccal swabs are easy and painless to collect, they are used in the majority of DNA paternity tests.

  • In a court-ready or “legal” test, each adult who is being tested should bring government-issued photo identification (e.g. driver’s license or passport) and if possible, government-issued identification for the child.

  • With an at-home kit, (non-legal) standard cheek swab specimens may be collected in a non-clinical setting such as a home. However, the DNA paternity test results for at-home collections are intended for the knowledge of the tested parties only.  At-home kits do not follow the strict chain of custody needed for use in a court of law.  These results are not generally admissible in a court of law.

  • Your privacy and security are important to us. Once samples are taken at the collection site, they are packaged in a tamper-proof bag for shipment to our DNA testing laboratory. Entry into our DNA testing facility is by restricted access only. All samples are bar-coded and all computer systems are secured. Results and case information are only shared with authorized individuals. For the protection of the tested parties, results are not released over the phone. All samples and DNA profiles are retained for a period of time (as required by legal requirements, accreditation guidelines, or if longer as agreed upon), but are destroyed after the requisite storage periods.

    Whether you choose a legal test for use in a court matter or a non-legal test for your own knowledge, trust LabCorp for exceptional quality and accurate results.
