What Is an Avuncular DNA Test?

An avuncular DNA test evaluates whether a biological relationship exists between a child and an alleged aunt or uncle. This type of testing may be useful when the alleged father is unavailable for testing.

  • Alleged father unavailable
  • Family relationship verification
