Benefits of having mother tested in paternity test?


Q: The company that i’m looking into charges extra to test the mother as well. i know they don’t need the mothers dna to determine paternity but it helps to screen out the genes of the mother so they can compare just against the father. but it’s not needed, so are there any other benefits?

A: You are correct, in that including the mother in the DNA paternity test allows them to isolate the genetic material that came from the mother. Testing the mother’s DNA increases the likelihood of a conclusive result for any DNA test. Though rare, with out including the mother, an inconclusive result is possible. Identigene, the lab that I work for, strongly encourages including the mother in DNA paternity testing. Because including her provides a stronger result, they do NOT charge extra to include her.
