How Does an Infidelity DNA Test Work?

Like standard DNA tests, infidelity testing requires comparing biological samples. In these cases, we typically analyze a sample left behind by a partner or a suspected third party and cross-reference it against your own DNA to rule you out.

We accept various types of alternative samples, which can include:

  • Bodily Fluid Samples: Found on sheets, undergarments, or clothing fabrics.
  • Secondary DNA Sources: Items like hair (with the root intact), used dental floss, cigarette butts, or nail trimmings. (Note: Viability varies depending on the condition of the item).

Our Simple 4-Step Process:

  1. Gather the Sample: Securely collect the material or article containing the DNA sample. Try to handle it with gloves or a clean ziplock bag to avoid cross-contamination.
  2. Provide an Exclusion Sample: You will typically provide your own DNA sample (via a quick, painless cheek swab) so our lab can rule out your own genetic profile from the evidence item.
  3. Discreet Local Analysis: Bring the samples to our NW San Antonio clinic. Our certified lab professionals process the samples safely and efficiently.
  4. Get Certified Results: We deliver reliable, secure, and conclusive results directly to you the moment they are available.

Please Note: While infidelity DNA testing provides personal peace of mind and definitive clarity, these tests are generally for informational purposes and are not court-admissible.
