The alledged father and I met to have a DNA test. I am the child in question. Prior to performing the buccal swab DNA test the man went into the bathroom and then came out and spit a large amount of saliva. He then proceeded to just suck on the swab. He did not wipe the inside of his cheeks. Is it possible to place the saliva and cheek cells of another person into ones mouth and then place the buccal swab into the saliva to absorb the saliva and cells. I have not felt comfortable about this test since it was done. Needless to say, the result came back and said he can be ruled out as my father. Have you ever heard about anybody tampering with tests like this.
