DNA test should be a most after the birth of a child because the high rate of paternity fraud is becoming too much this day's.
I was a victim of paternity fraud and I know how painful it was so heartbreaking, in my case the child was just 5 months and I decided to run a DNA test, but the mother of the girl said I will never run a DNA test on the little baby so I decided to run it without there notice and low and behold the child was not mine 0 paternity I was emotionally down and that is just for a 5 months child what if the child has grown to 10 or 15 years of age it would have been so bad for me.
So I will advise all men to run a DNA test when you feel the need to, don't let your woman blackmail you emotionally by saying you are wanting a DNA test because you don't trust her don't fall for that go ahead and run it every man deserve the right to know if truly the child his fathering is his or not.
