Determine the likelihood that two individuals are related as first cousins.

Confirm whether an alleged mother is the true biological mother of a child.

Step-by-Step

Step 1 - Arrange for an Appointment

Order your legal DNA test with ease, and let our DNA coordinators guide you through the process. We’ll work with you to schedule a convenient appointment for sample collection at one of over 1000 specimen collection locations across the US.

Step 2 - Prepare for the Identification Procedure

On the day of the appointment, you will be required to bring the following:

  • 2 pieces of legal identification: 1 with the patient’s photo (e.g. drivers license or passport) and 1 secondary piece of identification
  • Passport photos for each patient who is participating in the test

Genex follows strict identification procedures during the time of your appointment. During the appointment, all patients are positively identified by a rigorous identification procedure:

  • All patients are required to bring photo identification to their appointments. For children, a birth certificate or similar is appropriate.
  • The specimen collector will verify that the patient’s provided photograph matches the patient
  • A right thumbprint is obtained from all patients during their appointment. For infants, a right footprint is obtained for identification purposes.

Please note that these identification procedures are required only if you are using the results in court. If you need the results of the test for private knowledge only, and will not be using them in court, you can choose the private home test.

The strict-chain-of-custody procedures are required to ensure that the identity of all patients can be verified. The strict identification procedures allows different members to attend appointments at different times or even in different cities. Immediately after sample collection, strict chain of custody procedures are followed to ensure the integrity of the specimen during transport and processing.

Step 3 - Wait for Results

The average turnaround time for DNA paternity testing is 1 to 2 business days from the day that our laboratory receives the samples. Full payment for the DNA testing services must be received before the results are released. For legal testing, detailed results are sent to the individual requesting the DNA test unless otherwise requested. Results will only be released to individuals with proper written authorization.
