Three rows show tissue, blood, and hair samples labeled "Good," "Bad," and "Ugly." Good samples appear clean and ample; bad samples are inadequate, and ugly samples are contaminated or insufficient for DNA testing.

When collecting and sending DNA samples to the RAAA office, please keep the following guidelines in mind to ensure timely and accurate processing:

Submit Samples Early

DNA testing does not offer a rush service. Submit samples well in advance to avoid delays and ensure results are returned on time.

Ensure High-Quality Samples

Sample quality is critical to successful testing. Inspect all samples before submission. Low-quality samples will be rejected and not forwarded to the lab. Refer to the first page of the DNA order form for collection tips.

Sample Collection Guidelines:

Hair Samples

  • Do not cut hair – DNA is located in the follicles at the root. No follicles = no DNA.
  • Place the hair on a hair card with follicles secured under the sticky film. Secure at least 30 follicles.

Blood Samples

  • Completely fill the circle on the card, and allow the blood to dry fully before closing.
  • Use a sterile needle to collect the sample.
  • Do not submit blood samples for twins due to the risk of in-utero contamination. Hair or TSU samples are recommended instead.

TSUs

  • Each tube should contain tissue, liquid, the green ball, and a visible red stopper.
  • Do not collect tissue from dirty or tattooed areas, as this can contaminate the sample.

Include Required Documentation

All DNA samples must be accompanied by a completed and signed order form and payment. Incomplete submissions delay processing.
