While it is not always the mother's fault, a man sometimes has to make sure that the child in question is his or not. For those people who do not have hundreds of dollars to spend on legal fees or paternity tests through the court system, there is a home DNA paternity test available. These home DNA paternity tests can be bought at a store or online from $100 to $300.
