Sibling Testing

Sibling DNA testing can be legal or private. Sometimes the alleged father is not available. Comparing his children can help determine paternity. iTest DNA is the more knowledgeable source for sibling testing.

Sibling DNA Testing is based on two key ideas.
  1. Do the siblings have the same mother?
  2. What are the genders of the alleged siblings?

It is very important that every effort be made to include one or both mothers in testing. A sibling DNA test is not always a 99% or 0% result. However, iTestDNA can help you interpret the results.

iTestDNA offers the following DNA tests:

  • Full vs Half Siblings
  • Full vs Unrelated Sibings
  • Half vs Unrelated Siblings
  • Y Chromosome Testing
