Ideally all paternity tests should include the mother’s DNA samples. It may sound somewhat illogical because you are looking to confirm the paternity of the child. However, having the mother’s sample means that we can neatly map out and exclude her share of genetic inheritance in the DNA of the tested child. We can still provide accurate results without the mother sample but with it, we can give you even more accurate results. If we test without the mother, you can expect a 99.9% probability if the tested father is the biological father. If we test with the mother, this probability increases to 99.99%.
