Is it a violation of rights to use someones saliva after kissing them for a DNA sample ?

During a party, a woman submits a saliva sample from a recent kiss to screen her potential boyfriend's DNA. Is she violating his rights by doing this without his knowledge ? Is this in any way similar to preforming a background check ? How much would a DNA screen reveal about someones personality and intelligence ? What about their future health?



Please answer all, and I will give you best answer points ! Thanks !Is it a violation of rights to use someones saliva after kissing them for a DNA sample ?
I took Biology 2 years ago, so the information is not exactly fresh but no matter what is she is using something that belongs to him without his consent she is violating his rights, because his DNA is obviously his property. DNA could be a way to do a background check, because nobody has the same DNA. Personality and intelligence are probably very vague in a background check, because you cannot determine these things with just a saliva sample, they would need to run tests. Their health should be fine, because it's not like the women is going to give back the DNA, once its gone, its not coming back. Although the fact that she's submitting the Saliva from a kiss, wouldn't it need to come from her mouth, and mix with her DNA. So all the DNA she submitted may not even be valid.Is it a violation of rights to use someones saliva after kissing them for a DNA sample ?
1. She could never prove it was "his"

2. Extracting any bodily fluid without the donors consent is illegal

3. This is nothing like performing a background check. This is illegal search and seizure and pure entrapment under the law.

4. IF the DNA could be isolated from hers, it would tell a great deal, but the saliva would actually be from two different people, and would contain the traits of both, not just her boyfrienf.

5. The sample is corrupted and unusable.Is it a violation of rights to use someones saliva after kissing them for a DNA sample ?
Last answerer (chocolate) was spot on, couldn't help but agree, also I think,,,, 'Why not just ask the boyfriend for a DNA sample' ?..... Surely that would be a honest approach?.... 'Honesty is the best policy' ?.... You don't mention 'Why'?? i.e. Obviously apart from your inability to judge (discern) a good character from a bad character? by relying on your own senses? or own mind?, and strangely there is no crime to speak of? Just the hope of matching dna to a crime dna database?,,,, i.e. assumed guilty with no crime immediately present?,,, it seems like a personal vendetta to go at it from that funny angle?,,, i.e. 'guilty before proven innocent'?....Is there any reason to assume someone is guilty of a crime?,,, if so; then you (possibly) justifiably present your case to that person, as a justification to take their DNA,,, otherwise it all seems very strange,,,, and could destroy the relationship when the boyfriend is proven innocent, and God forbid finds out an entire investigation into his life took place without his knowledge, knowing that the girlfriend assumed he was guilty and didn't stand her ground and defend his innocence from the word go, vehemently; would certainly damage the relationship, possibly beyond repair,,,, The boyfriend would really have to love her a lot, to take her back, after being hurt from being doubted like that.... DNA won't tell you much, Twins can be massively different in personality,,,, plus human errors occur,,, even a 1% risk is a risk your giving someone, i.e. It's a 1% risk of 'false imprisonment' they didn't have before they met you....
Do you take all your first dates DNA,,,,, or is he just the lucky one.
