During parentage DNA testing, the laboratory identifies the length of the two alleles found at each locus. The DNA grandparent test is generally used under circumstances where the alleged father is not available for testing. When the probability of paternity is 99.99% this means that the man who has been tested is 99.99% more likely than a random man to be the biological father of the child.
