Hbud Posted December 11, 2007 Share Posted December 11, 2007 Hello all! ? If urine were passed through a medium...a filter of some sort....would it produce filtered urine? would the urine still be conciderd urine? I want to find out if urine can be voided through a filter and cleaned of toxins or markers that could be used as information for a case of genetic discrimination against the person making pee pee in the cup.

iNow Posted December 11, 2007 Share Posted December 11, 2007 I guess that would depend on 1) the definition of urine, and 2) what type of filter was used (in essence, what was removed by the liquid passing through it)? Genetic discrimination? Can you elaborate? I'm just curious. I really don't understand what you are asking, but perhaps someone else here will know oodles of info on this subject. I do know that you can distill it and drink it. Saw it on Survivorman. He was in the desert one week, dug a basketball sized hole, peed in it several times, covered it in plastic with a cup within, and then the sunlight evaporated pure water from the urine which collected on the plastic and dripped back into the cup. Good knowledge to have. Sorry... I'm rambling. Quick answer? Anything which first passes through a filter is itself considered filtered. Link to comment Share on other sites More sharing options...

Glider Posted December 11, 2007 Share Posted December 11, 2007 To filter a urine sample of any genetic markers, toxins or other chemicals, would need an extremely good filter. We're talking at least dialysis quality. The result would be pretty much just water. Anybody testing it would know it was not 'straight' urine.

YT2095 Posted December 11, 2007 Share Posted December 11, 2007 High doses of Ionising radiation would probably make most of the genetic material unreadable and still leave the soln as urine. but as for Filtering say with a molecular sieve, as Glider said it would come out as water more or less, and would certainly take time to do unless you had vacuum apparatus with you.

DrDNA Posted December 16, 2007 Share Posted December 16, 2007 Are you refering to "discrimination" in the form of insurance rates or insurability? "Toxins" and genetic discrimanation? Although it is possible and can be done, most genetic testing does not utilize urine. It is much more easily accomplished with blood, hair, cheek scrapings or even spit. DNA extraction and amplification from urine can be expensive and maybe not all that accurate because urine is clean when it leaves the kidneys and the only (or most of the) DNA present would be from cells sloughed off as the urine flows through the urinary tract.....all genetic testing is pretty expensive. Can you point me to a specific case where this is being done (for "discriminatory" purposes)? I'd like to learn more about it if it is occuring. PS: if you want to try to pass a pee test for drug use, you'd be better off with a warm (exactly 98.6 deg) bag of your clean friend's juice.....but that is hard to get away with, since they like to watch. as mentioned by someone else above, an unusually clean liquid without the usual markers and background signals would set the bells off.

John Cuthber Posted December 16, 2007 Share Posted December 16, 2007 What does discrimination against people who take canabis have to do with genetics? You could filter THC out of urine fairly specifically but it would take quite a lot of R and D to get it to work. You would be talking about molecular imprinting of polymers or some such. Even if you culd get that technology sorted out there would still be the practical problem of explaining "hang on while I filter my urine sample through this suspiciuos gadget" when you gave the sample. It migt be easier to stay within the law. Link to comment Share on other sites More sharing options...
blike Posted December 16, 2007 Share Posted December 16, 2007 I'm guessing the OP has to take a urine drug test and wants to purify his urine. Link to comment Share on other sites More sharing options...
iNow Posted December 16, 2007 Share Posted December 16, 2007 ...how do americans protect thier privacy rights when peeing in a cup? They vote for someone who prizes these values and who will enact such protections during their term. Link to comment Share on other sites More sharing options...
