The tests for which we most often see 99% or higher probability of relationship are paternity, maternity, and grandparent testing where both paternal grandparents participate. So now there is no father to do dna. Have more? There are two common possibilities that can yield an inconclusive DNA result when testing for paternity: 1. Excluded means that the potential father does not share enough DNA (the match percentage will be 0) and is therefore excluded from being the father. Special specimens require a $400 fee plus the lab testing fee. Or else mismatch is not possible once probability is calculated more than 99% (99.999) (not excluded)???????
