How accurate are DNA tests to exclude the father?

Question

Does anyone know of a mixup?

Answer 1

The DNA test on a baby compares the DNA of the baby with that of the mother and possible father. If there are no DNA strings present of the father then he is not the father. A mismatch is 1 in a billion.

Sources of error could be
1 in taking sample-deliberate or accidentally taking or contaminating sample
2 mix up at laboratory

A laboratory is very concerned to avoid contamination or mix up in testing.There are multiple safety checks to avoid this.

When I take samples for testing the baby and alleged fathers sample are taken at the same time-with proof of the fathers identity(either I already know them or passport) to avoid substitution.

Home testing sampling depends on the taking which is outside labs control.

So the results don't lie.

Answer 2

Yes there have been mixups, but they are VERY rare. The test is 99.98% accurate. The mixups have come from lab errors, not because someone chose the right person and it said it was wrong.

Answer 3

No they are very accurate as I have heard UNLESS the "father" has two forms of DNA then it will harder to recognize. You can learn more about DNA on the site I have described below:

Answer 4

dna is considered proof in any court of law, the results are considered 99.999% accurate.

Answer 5

highly accurate, you have to accept the results. maybe if the two men were identical twins, but otherwise they are dead on
