Reply to comment by ScienceIsSexy420 in ELI5: What are the chances of getting two different DNA/Paternity test results from two accredited lab? by Beneficial-Elk-8207

Yep, the way they get to their answer might be different but it should still give the same answer (you are the father yes/no) if the method is sound.

Do paternity tests give a certain yes or no now? I needed one for citizenship purposes years ago and the report we got only had a percentage, like, “there’s a 99.995% chance of paternity” or some very high but slightly under 100% percentage, but not a solid yes or no. They explained to us at the time that no test could be 100% certain, so a yes or no answer would be invalid.

That's correct, there's no true 100% certainty. But as a matter of statistics, you can interpret some threshold level match as an effective yes/no.
