Has my DNA sample reached the lab?

Samples mailed from within the United States typically reach the lab within 1 week. To track your kit’s progress to the lab, use the return tracking link TruDiagnostic emailed to you. This is also available on your profile homepage.

Delivered vs. Received 

There is typically a delay between the time a sample is marked as “delivered” on the tracking information and the time it is scanned as “received” by the lab. Occasionally, this delay can take up to a week. A kit is marked as “received” by our system when it is physically opened at the lab and the kit barcode is scanned.

It is not unusual for kits shipped at the same time to be received at the lab at different times. You will receive an email when our laboratory completes the accessioning process and scans your kit barcode. The status of your sample will also update on your profile homepage.

When will I receive my DNA test results?

Important: Processing times are estimates, and should not be considered a guarantee that your results will be returned by a particular date. While samples are processed in the order in which they are received, some samples may require additional steps to be processed successfully, therefore extending the processing time. Sample processing takes approximately 4-6 weeks from the time your sample is received at the lab. You can find up-to-date information regarding your sample status by logging in to your TruDiagnostic account. In addition, you will receive email notifications at the address associated with your TruDiagnostic account for the following processing milestones:
  • When your sample has been received at the lab
  • In the event of an analysis failure due to insufficient DNA or a low call rate
  • When your results are complete and available to view within your TruDiagnostic account
As soon as processing is complete, the lab will report your data. We will then compute your results and make them available to you through our website. You must log in to your TruDiagnostic account on our secure website to view your information. We do not include a printed report through the mail or provide your results by email.

How can I view the status of my sample?

Important: Our estimated sample processing time is 4-6 weeks from the time your sample reaches the lab. Actual sample processing times may vary. Your TruDiagnostic homepage displays the status of your sample as it moves through each step of processing, from the time you order to the time you receive your results. Results typically take 4-6 weeks from the time a registered sample is received at the lab.

Step 1. Register your Kit

Before you submit your sample, make sure to register your kit to a TruDiagnostic account. To begin, visit https://trudiagnostic.com/register. Once you have successfully registered, use the return tracking link available on your profile homepage to track your kit’s progress to the lab. Samples mailed from within the United States typically reach the lab within 1 week.

Step 2. Sample Arrived at the Lab 

We’ll send you an email when your sample is received at the lab and the barcode has been scanned. Once a sample is received, it enters the queue for processing.

Step 3-4. Prepping your Sample and Extracting your DNA

These steps include the time a sample spends in the queue at the lab, as well as the visual inspection of your sample, DNA extraction, and quantification of DNA from your sample. If your sample does not yield sufficient quantities of DNA, this step may be repeated.

5. Evaluating your Biological Age

This step refers to the analysis of your blood sample. We evaluate your biological age using your sample on our custom chip.

6. Review the Data

Quality review is where the data returned from a set of samples is reviewed to ensure that it meets our standards for call rate and accuracy. If your sample does not yield a call rate that meets our standards, this step may be repeated.

7. Final Computation 

Samples proceed to this step after they pass quality review. This step compares sample data with the rest of the TruDiagnostic database to generate results for features like DNA Relatives.

8. Your Results are Ready 

Once the computation step is complete, data is loaded into your account and your reports are made available. You will receive an email when your results are ready.

Why do some DNA samples fail?

There are several reasons why analysis of a sample may not be successful, and it is not always known why it is more difficult to analyze some samples over others. If necessary, the lab will make multiple attempts at all stages of the process in order to provide results. If your sample has to repeat one of the processing steps, your sample status will update; both DNA extraction and epigenetic testing may be repeated. In the event of an analysis failure that requires a second sample be provided, you will see a notification within your account.

Replacement Sample 

You will also receive an email in the event a replacement needs to be requested. When submitting a replacement sample, we recommend reviewing the tips on providing a good sample, including:
  • Drink water prior to collection
  • Warm your fingers
  • Test on the side of your fingertip. The side has an excellent blood supply and allows for the least painful fingerstick. Any finger may be used for a fingerstick.
  • Collect the recommended volume of blood. The recommended volume of blood is 3-5 drops (a minimum of 250ul).
  • After collecting your sample, invert the tube several times to mix the sample and anticoagulant.
Receiving a Refund

In the event of a second sample failure, you will be able to request a refund for the purchase price of your kit after subtracting shipping and handling charges. Review our Full Refund Policy.

What is TruDiagnostic’s quality review process?

As part of our quality control process, an anonymized set of data is reviewed to ensure that it meets our quality standards prior to being entered into your account. The data is reviewed for accuracy. Accuracy checks include comparing the barcode on the collection tube against the barcode entered during registration, as well as instruments checks and calibration. Occasionally, batches of samples are flagged for additional quality review. This does not reflect  the quality or viability of a particular sample, but simply the overall set of data. In order to ensure you receive information that meets our standards we will perform additional review steps prior to releasing data.
