Cheating Spouse DNA Testing

Are you concerned about a cheating spouse? Perhaps you found clothing or bedding with suspicious stains. Paternity Northwest can help provide conclusive results to confirm or refute the presence of semen, saliva, and male/female DNA on suspicious items.

We understand that each case is unique so we offer multiple testing options to best serve your needs. Results are completed in as little as 5 business days. Rush testing options are also available in most cases.

Choose from any of the following testing options:

  • Semen Detection – This test will confirm if semen is present.
  • Saliva Detection – This test will confirm if saliva is present.
  • DNA Detection – This test will confirm the presence of male or female DNA. Both autosomal DNA Detection and Y-STR DNA Detection options are available.
  • DNA Comparison – This test will compare your DNA against any DNA found on the evidence sample to determine if you are a contributor. Both autosomal DNA Comparison and Y-STR DNA Comparison options are available.
