Answers to our most Frequently Asked Questions can be found below. If you do not find an answer to your question(s), please do not hesitate to use our Contact Us form and we will respond within 24 hours.

What are your payment options?
We use PayPal as our credit card processor and accept all major credit cards. We also accept money orders.

How long does it take to get the results?
This answer depends on the type of test. Most casework is completed in as little as 2 business days from sample receipt. Rush testing options are also available in case results are needed earlier than 2 working days.

How will I receive my results?
Endeavor DNA will email your test results when they are complete. If you’d like to receive your results by mail, you may request that option for an additional fee.

Can my test results be used in court?
Our Legal DNA testing services can be used in court. Our DNA services employ the use of strict chain of custody documentation, impartial sample collection, and stringent testing requirements to ensure the authenticity and validity of our test results. Testing services labeled “Peace of Mind” or "Informational" are not admissible in court. Learn more about the difference between Legal and Non-Legal DNA testing by clicking here.

Are the results confidential?
Yes. Your results will be held in strictest confidence.

What if I want to test more than one child or alleged parent?
Additional family members can be included in the tests. Additional charges apply.

Will you accept profiles from third party laboratories for comparisons against new samples?
Yes, so long as the tested STR loci provided by the 3rd party laboratory match the STR loci tested by Endeavor DNA Laboratories.

How accurate is the paternity test?
The industry standard to establish paternity has long been 16 STR loci. Endeavor DNA Laboratories tests 22 STR loci to determine paternity, so our tests are extremely accurate. The STR loci we test are designed to meet both CODIS and European testing standards and provide the highest discrimination of any autosomal STR kit. In general, if the alleged father shares alleles with the tested child at all tested markers, then the probability of paternity will be at least 99.9%. If the alleged father and the child do not share the same genetic markers, he will be excluded as the father with a 100% probability.

Does the mother have to be tested as well?
It is always good to include the mother but it is only required for cases involving fetal demise and birth certificate changes. For all other casework, the mother may not have to be included. Please contact us if you have any questions.
