Dna results explanation?

My results came back stating "Peter Rodriguez is not excluded as the biological father of Jonathon Rodriguez. The next paragraph states "The Combined Parentage Index is 348,886 (corresponding to a Probablity of Paternity of 99.99%)". Then the alelles are listed. 15 were tested. One of my son`s numbers matched one of the alleged father`s(Peter) for each and every alelle. Does this mean he is the father? The only thing that gets me is that there is no percentage if he is the father or not. Isn`t there supposed to be 0% if he isn`t and greater than 99% if he is the father? Please explain. I`m pretty sure the results state that he is the father though. Just need confirmation from someone who experienced this before. By the way, the DNA paternity test is an over the counter Identigene test which was sent with payment to a lab and i received the results a week later. Please let me know. :)
