DNA Tech Lab (DTL) Paternity Testing Process

  • What is the age limit for DNA tests?

    There is no age limit on DNA tests. A DNA test can be performed on an individual at any age.
  • What is a buccal swab?

    Buccal swabbing is a non-invasive way to collect DNA samples from the cells of a person's inner cheek. Buccal means cheek or mouth. A buccal swab resembles a large cotton tip. It is used to collect cheek cells by rubbing the inside of the cheeks. A buccal sample is as accurate as a blood sample. Check Sample Accuracy page to learn more.
  • What if the father is not available?

    It is possible to establish paternity even without doing an paternity test. Paternity can in fact be established by testing relative of the alleged father or your sibling. If only the child and relative of alleged father are tested, the results may not be completely conclusive. If the mother's DNA sample is available for the testing, the results will be more conclusive.
  • How long can I get my results?

    Once all the specimens have been received at the lab, results take an average of 3 business days. Rush results are available upon request.

If you're purchasing a paternity test, you've no doubt thought a bit about it beforehand. You've probably looked into what the process entails, compared prices from various companies and thought about the implications of knowing paternity and how that will change or impact the lives of the people involved in the test.

Legal Paternity Test or Personal Paternity Test?

One other item you may have considered is whether you will need a court-admissible legal paternity test or not. At DNA Tech Lab (DTL), there is no difference in the way we test samples between a personal home paternity test and a court-admissible legal paternity test. Once you decide on what test you’ll need, follow the directions below if you're wanting a personal home paternity test or click here if you want to find out more about our court-admissible option.

A lot of work goes into the DNA paternity testing process from the laboratory side of things, but lucky for you, the process for our customers is a cinch. Below are the basics of how the DTL process works from start to finish as well as a few tips that may help you out along the way.

What You Do

1. Purchase the DTL Paternity Test Service

First, you'll need to purchase the DTL Paternity Test Service. You can do this by calling DTL, purchasing a Paternity Test Service on our website. The service will cost you about $???, depending on the number of participants and sample you provide. 

2. Collect your DNA samples

Next, you'll follow the directions to collect DNA samples. Fill out a sample envelope for each participant and be sure to fill out the order form. Collect samples from each participant by gently rubbing special buccal swabs included in the kit on the inside of the cheek for 30 seconds to collect cells. Place sample swabs in the corresponding sample envelopes. If the sample envelopes become damp, let them air-dry before putting them in the mailing envelope.

3. Mail paternity testing samples and order form to DTL

Lastly, you'll mail the samples and order form to DTL in the pre-addressed, pre-paid envelope included in the kit. It is important to remember that this method of sending samples can take anywhere from 7-10 days to arrive to our lab. Once samples arrive, testing takes three business days. If you need your sample to arrive earlier, you'll want to consider another mailing option. If you have questions, please contact us! We also have an option if you would like testing completed in one business day: read more here.

Now that you’ve done your part, DTL will step in and do the rest. Check out the brief overview of what happens to your samples when they arrive to DTL.

What We Do

1. Paternity test accessioning

Your samples first arrive to our accessioning department where the information on your sample envelopes and order form are entered into our database. Each sample is assigned a sample number and the group of samples are assigned a case or reference number.

2. DNA Extraction

Once all information has been added to our database, samples are prepared for DNA extraction. During this process, the cheek cells on the sample buccal swab are purified of proteins or contaminants and the DNA is separated from the cell.

3. DNA Amplification

Next, DTL laboratory technicians prepare the extracted DNA for amplification by checking plates and samples and pipetting. During the amplification process, DNA segments are duplicated for testing.

4. Testing

Finally, segments of DNA are compared between the alleged father and child by our genetic scientists. If the mother's sample is included, her sample will also be used to get results for paternity. A report is then generated and will send your after being reviewed by our experts.

We hope this explains the entire process for you, from start to finish!
