Q: I had a paternity test done and it came back 99.99% probability. A friend of min also had a paternity test done and his came back the same way. He went and had a blood test done and it came back at only 21.9%. Which one is more accurate? Is it possible that the people screwed up on my results. If so then where can I have a blood test done?
A: In at least one case I was involved with a few years ago, a "buccal swab test" (saliva test) came back with a 99% probability of paternity, but a subsequent blood test showed that the child was not my client's. A blood test is more accurate than a buccal swab test. It is certainly possible that the test was screwed up, and generally if you ask the court for a blood test (not a buccal swab test) and offer to pay all the expenses for it, you can frequently convince the judge to allow it.
