This test is to identify the true biological father of a child.
If the alleged father is not related to the child, then the results will be 100% certain. If there is a relationship, then we expect a result that will give you in excess of 99.999% certainty that the alleged male is actually the father of the child. Whilst the mother need not participate (notwithstanding any consent required for the child),we strongly advise that she does so, in order for us to achieve the above level of certainty.
Without the mother being tested, you can expect a result of approximately 99% certainty, but this can sometimes be lower.
