Paternity Results

DNA Worldwide Paternity Test results are simple to understand. All tests look at at least 21 DNA Markers, and many test up to 46 DNA Markers. This provides a result that is at least twice as accurate as any other DNA test in the UK.

Every DNA test report should include the full details of each person being tested along with their DNA code and a clear and simple conclusion. This should read either:

  • 99.999% Probability of paternity = The tested man is the father
    • Could also be written as "It is practically proven"
  • The tested man is excluded = The test man is NOT the father
    • Could also be written as 100% Exclusion
