DNA Processing Consent Form Requirements

There are several key points to remember when mailing your completed DNA sample to us.

  • The DNA Processing Consent Form must be included along with your DNA Sample. If the DNA Processing Consent Form is missing from your kit or damaged, a new one can be downloaded and printed here.
  • The name of the DNA donor on the Processing Consent Form must match the name on the kit.
  • Minors under the age of 13 cannot be DNA tested regardless of parental consent due to international privacy laws, so the month and year of birth on the form is required.
  • You cannot re-label collection kits with a kit number different from the one that is printed on the label for that collection kit. If you have lost or damaged your kit, Customer Service will be happy to assist in getting a replacement sent to you.

IMPORTANT: The DNA Processing Consent Form must contain the name, DOB, genetic sex, and signature of the DNA donor, regardless of the person who purchased the test. The name of the tester MUST be on the correct line, so read carefully.

Replacement Kits 

When a replacement kit is ordered, there is a chance that the original DNA collection kit sent to you was delayed rather than lost. In such cases, when you receive the replacement kit, it is crucial not to use it for any other individual. Submitting samples from different individuals under the same kit number can cause significant delays in testing.
