This is because we have no way of verifying that the DNA submitted actually belongs to the names of the people attached to them. Collecting DNA is a simple process. For a home test, if all participants cannot witness each other swabbing and/or cannot trust one of the people to be honest with the DNA they submit, then we always recommend that they do a legal test instead.

When a probability of paternity comes back as 88% that usually means the result is inconclusive. For the suggested paternity scenario with a mismatch at only one locus, this would be indicative of a mutation and the PI for that locus would NOT be set to zero but would be calculated based on the mutation frequency for that locus. My boyfriend did a dna test with my daughter with but without my dna. The two siblings share a lot of DNA, but theyre not identical. I apologize for the late response, Reena. I began researching online about false positives and that even though all of my alleles match my daughters, theres a possibility that one of the alleles could have come from the mother instead of me.

If the swabs had been contaminated in any way, the lab would not have issued results at all. You and I probably match at some loci. Can we assume its a positive test since there werent any true mismatches? Thank you for your question Reena. 2) Does it cost extra to include samples from the mother in the overall test?

Suppose a sample sent to the lab is weak yield only 6 markers, (mother is also tested) So my daughters father went and got a paternity test done without me and the results stated that the origin of DNA was not found or something like that so the results were 0% what does that mean.
