Understanding your DNA Testing Results

Our test results give you a detailed description of how the test is conducted, what the results are, and what those results mean.

We take great pride in making our tests both easy to understand and scientifically sound with every test being run twice exceeding all ISO 17025 and AABB requirements.

Below are links to pages that help fully explain how we carry out and report your results.

2. Understanding Close Relationship Results

In Addition we've provided a sample version of several of our results, so you have an idea of what to expect when you receive them, and you can better understand how we've arrived at the results.

• Paternity Test Inclusion Example - (is the father)
  
  This example of a DNA Worldwide Paternity Report shows the alleged father as "included" as the possible biological father. To be included, the Combined Parentage Index must be greater than 100 (the Probability of Paternity must be greater than 99%). DNA Worldwide paternity probabilities regularly exceed 99.99%.

• Paternity Test Exclusion Example - (not the father)
  
  This example of a DNA Worldwide Paternity Report shows the alleged father as "excluded" as the biological father. To be included, the Combined Parentage Index must be greater than 100 (the probability of paternity must be greater than 99%). DNA Worldwide probability of paternity regularly exceed 99.99%.
