FAQ

Why should I do a DNA ancestry test now?

Analyzing patterns in your DNA reveals more about your ancestry than your family tree alone. Next Generation Sequencing Technology (NGS) is unsurpassed for ancestry analysis and is considered state-of-the-art by scientists studying human history. Until now, NGS technology has been too expensive for consumer ancestry analysis, causing other DNA ancestry services to use older technologies such as PCR or DNA array based genotyping. We’re excited to announce that scientists at Centrillion Biosciences have developed laboratory chemistry and software that makes genome-wide sequencing based ancestry accurate and affordable. Now you can enjoy DNA ancestry information based on the most advanced technologies: genome-wide DNA sequencing.

We know that personal privacy is very important. That’s why at TribeCode, we have developed a proprietary method that reveals your ancestry information without compromising your private medical information. Your TribeCode account is secure, but ensure that you choose a sophisticated password that would be difficult for someone else to guess.

How do I register my kit?

To register your kit, visit www.tribecode.com/kit-registration or scan the QR code located on the instructions in your kit to for easy registration on your phone or device. For more help, watch our tutorial at www.tribecode.com/tutorial.

Where can I find my registration barcode?

Your registration barcode can be found on the bottom of your Tribecode box, the top of the plastic container within the kit, the side of the collection tube, and on the return envelope. For more help, watch our tutorial at www.tribecode.com/tutorial.

How do I register my kit if multiple kits were ordered at the same time?

Distribute the kits to the intended recipients. Each person should register their kit with the associated barcode. After registering, please do not swap kits or saliva collection devices.

Why do you need so much information from me?

On very rare occasions, samples can get mixed up in the lab. Your self-reported information allows us to ensure that we are sending you accurate results. Additionally, your information can help improve data analysis in the future. By providing this information, you are helping yourself and other customers by improving the process and accuracy of results. We therefor encourage you to answer these questions to the best of your knowledge.

How do I collect my saliva sample?

Fill the collection tube with 2mL of saliva, squeeze the liquid preservative into the kit, close the cap, and shake vigorously. Further instructions for collecting your saliva sample are included in your TribeCode DNA Ancestry Test. For more help, watch our tutorial at www.tribecode.com/tutorial.

How long does my collection kit last?

Under optimal conditions (room temperature), your collection kit should last several months. However, for optimal results we recommend sample collection and mailing as soon as possible after you receive your kit.

How do I send my sample back to the lab?

Your kit comes with a self-addressed return envelope and a plastic biohazard bag. Simply put your filled collection tube inside the plastic bag and seal the bag inside the envelope. You may attach the required postage ($2.07 or 5 stamps) and drop in a mailbox, or pay for exact postage at any post office. Please send back your sample as soon as you collect it. Prolonged storage under certain conditions could affect the quality of your results. For more help, watch our tutorial at www.tribecode.com/tutorial.

I forgot to register my kit but sent it back already! What now?

Call or email us at customerservice@tribecode.com.

How long until my results are available?

Your results should be available within 6-8 weeks from the date your sample arrives at our lab.

How can I check the status of my sample?

Your sample status will be updated every step of the way. You can check the status online through your TribeCode account. You will also receive an email at the email address associated with your account when your results are available to view and share.

What are the causes of low DNA yield from saliva?

Even when all instructions are followed correctly, some saliva samples do not produce sufficient yield or quality of DNA to enable good quality sequence analysis. If your first sample fails due to insufficient quantity or poor quality DNA, a replacement kit will be issued at no additional cost. 

There are a number of factors that can cause low DNA Yield or poor sample quality. If the DNA preservative is not adequately mixed in the sample the DNA yield will be low. Also, if the sample is exposed to very warm temperatures during collection or shipping, (>30oC/85oF) DNA can degrade. Some people just don’t have much DNA in their saliva. This can be due to physiology, health status, or medical treatment.

Do I need to confirm my email address before I can view my results?

Yes, you need to confirm your email address when you create your account.

Can I view multiple sample results on one account?

Yes, but you can only view ancestry results for samples that were registered to your account. In purchasing the kit, “Who will be using this kit?” determines the account that the kit will be registered to. This is the account where the results will be available to view.

How can I share my results with my friends and family?

To share your results with others, navigate to your profile photo in the upper-right corner of your screen. Hover over this icon and click “Test Result.” Then click on the “Share Data” tab, where you will be able to share your results. You can also share your results by email or Facebook.

How can I keep my information private so no one else will see it?

Your information will always be private unless you share it with others.

What is a haplogroup?

A haplogroup is a term used to describe a group of people who can trace their ancestry back to one person. We display maternal haplogroup information (“Maternal Lineage”), which traces your ancestry from your mother to her mother to her grandmother, etc. through your mitochondrial DNA. For males, we also display paternal haplogroup information (“Paternal Lineage”), which similarly traces your ancestry from your father to his father to his grandfather, etc. through the Y chromosome. Males and females both have maternal haplogroup information, but only males will be able to see their paternal lineage.

Why do I have a different haplogroup from my family member(s)?

To begin with, children do not inherit their paternal haplogroups from their mother’s side of the family, nor do they inherit maternal haplogroups from their father’s side. Due to the nature of inheritance, it is common for parents to have different haplogroups than their children.

Otherwise, you may not have the same haplogroup as someone else in your family due to the genetic testing process. Some individuals may have been able to have more data generated than others, placing them on the same branch as a family member but with more specificity. Other possible causes are a recent mutation or mistaken paternal relationships.

Why sex assignment results can be ambiguous?

Sex assignment can be ambiguous due to a number of factors, both biological and technical. Our algorithm uses reference data and statistics to assign a sample as male or female. In some cases due to biological or technical reasons the algorithm will result in placing an individual in neither category.

What does a preliminary Y chromosome result mean?

Y chromosome results can be preliminary for some people for a number of reasons, including sequencing depth. Because we have been delayed in delivering reports, we recently posted some reports for which the Y chromosome results were still in progress. We posted these reports because we wanted to get the autosomal and mitochondrial results to you with no further delay. If your Y chromosome report is marked “preliminary,” we are working to refine and improve your Y chromosome information and will update your report when we have additional information.

What does the label “Native American Concordance” mean?

  • If you see this label on your report, it indicates that you possibly have Native American ancestry. We have observed that some customers with Native American ancestry have a pattern of South Asian and/or West Asian ancestry in speculative mode in their ethnicity composition. We are investigating our reference data and algorithms for the source of this concordance. We are also working on expanding our reference populations.
  • If you do not see this label, you may still have Native American ancestry. If your ancestors originated long ago or your percentage of ancestry is very small, we won’t be able to detect it or confidently identify it. Speculative mode in ethnicity composition detects any percentage greater than 1%. In some cases we find a very small percentage of East Asian ancestry, which may also indicate Native American ancestry because of the similarity between Native American and East Asian genetic makeup.
