yes there is dna in every part of your body including your fluids.
mmm… fluids.
There is DNA in every part of your body that contains cells. if your urine didn’t have any cells in it (it will) then it wouldn’t have DNA in it.
Actually, urine itself shouldn’t have any cells in it unless
1) it’s collected improperly, ie not a “clean catch”. Then squamous (skin) cells from around the urethra can end up in it (that’s why it’s important, for women especially, to pee a little first before collecting urine in a cup) or
2) the person has a bladder or kidney infection, which can cause white blood cells to end up in the urine (sometimes red blood cells too, but they don’t keep their nucleus and so are an unusual exception with no DNA). You could also end up with bacterial cells in the urine if you have an infection and those would contain DNA, but of course it wouldn’t be yours.
I think you can DNA from a fart, if I’m not mistaken.
