No, not a "home" DNA test. As I said in my post, a "legal" admissable DNA test involves sample collection by officials certified to do so, and a "chain of custody" for the sample. A home DNA test can provide an answer, but it's not admissable. A "privately done" DNA test CAN be admissable as long as it is done within the law and has a legally acceptable "chain of custody" for the sample.
A simple Google search for DNA testing companies will provide you with numerous services that provide legal admissable DNA tests. Here is one link for you, if you want more just Google it and you will find many.
