A paternity test is a test based on a blood group or DNA to check on a particular man as the biological father of a child. This is usually used to end the doubts of couples and parents who suspected their unborn/ born child is not theirs especially when they suspect that their partner is cheating on them.

This method could also be used for adopted children who wish to find their biological parents. This test usually takes up a few weeks but the result is as true as the blue sky in the day.

During the medival times when medical technology is as ancient as them, this method could have easily saved plenty of lives, saved many marriages and hush the mouth of the gossip mongers.
