What about a “dadchecksilver” test involving only one parent?

The dadchecksilver paternity test is more conclusive if we can test all three of the child, mother and alleged father.

A test without a sample from the mother will not provide the same degree of certainty as a test with samples from both parents, but nevertheless, we would expect to report a probability of paternity in excess of 99%. Please note that tests which do not involve the mother are not acceptable for legal purposes.
