If you have an item that may contain DNA for a Paternity, Sibling, Avuncular, or Grandparent Forensic DNA Test, and you are unsure if it is usable, we can help determine viability before you order a full Relationship DNA test.

Each case is unique and we accept many sample types including toothbrushes, razors, clothing, tissues, and stains. Results are completed in as little as 5 business days. Rush testing options are available in most cases.

In this screening, our professional DNA analysts examine the submitted item to detect human DNA, identify how many DNA profiles are present, and assess profile quality. This tells you whether the sample can support Relationship DNA testing such as Paternity, Sibling, Avuncular, or Grandparent testing.

When testing is complete, Validity Genetics DNA provides a written report explaining what was detected and listing all DNA profiles identified, along with clear next step recommendations.

This test does NOT contain a reference swab or compare any found DNA against other samples.

To compare your or your partners DNA against the DNA in the sample see our other Infidelity Tests (Advanced Infidelity DNA Test and Complete Advanced Infidelity DNA Test) .

Choose from any of the following testing options:

Instructions on gathering evidence for Infidelity testing

It is extremely important that all to be tested evidence is handled as little as possible. Gloves are recommended to prevent any extraneous contamination.

HOW TO COLLECT EVIDENCE (SPECIAL SAMPLES):
To gather special samples, please follow these instructions:

Step 1: Please label envelope with the following details (use one small envelope per sample):

• Sample name or description

• Collection Date

• Approximate age of sample (date when it may have appeared or item last used)

Step 2: Prep the sample to be mailed:

• If this is a clothing sample or fabric stain (for example a bed sheet) we recommend you send the entire item to our lab. Please indicate where the stain to be tested is*

  • If you decide the item is too large to send through the mail, the stained area may be cut out and mailed instead. Please leave one to two inches of space around the potential DNA

• If this is a smaller item (toothbrush, hair follicles, condom, etc), make sure it dry (please allow to air dry. Do NOT use a hair dryer or any form of heating device to force it to dry) and can fit inside the labeled envelope

• Do NOT place anything in plastic bags

Step 3: Seal samples inside labeled envelope:

• Place the special samples into the envelope

• Seal the envelope with tape

Step 4: Place samples together in a larger envelope and mail to our Laboratory:

• Compile envelopes containing special samples, oral buccal swab samples, and the completed paperwork together into a larger mailing envelope

• Mail to our laboratory using a traceable courier service (USPS, FedEx, UPS, etc)

  • Our Laboratory Address Is:

    Validity Genetics DNA

    500 South Main Street
