Men who require paternity tests, are you willing to do multiple paternity tests performed by a medical professional and under witness observation?

I’m seeing that a lot of men are insistent on getting “ease of mind” paternity testing to ensure a child is theirs. Personally, I feel that if a man is so concerned about being 100% certain whether the child is theirs or not, they should just adopt, which will allow them to be 100% certain.

Seeing as the women who are most bothered about being asked for a paternity test are women who are already 100% certain who the father is, there is a lot of damage that can be done by false or inaccurate test results. There is only way a woman can be 100% sure that the man is not falsifying results in order to get out of raising the child they have together; to have multiple tests performed by a medical professional under witness observation.

For the men who are insistent on their partner doing a paternity test regardless of circumstance, are you willing to pay for multiple tests performed by medical professionals under witness observation? Why or why not?
