How accurate are THC ''Utest''?

So I stoped smoking around febuary first, and had maybe 5 tokes between then, and now. The last one was this sunday.. I have a ''Utest'' piss tester for THC, I just tried it.. My results say I'm clean, with a very faint pink line.. How accurate is this test compared to the ones I'm going to get in a few days in Alberta? I have like, no fat on me, so maybe it is possible that I'm clean after 3 days..?

Anyone with experience with these tests, I'd love to hear your two cents.. Might just end up buying a perma-detox kit anyways, just to be safe?

 

well i've been drug tested multiple times from my parents and the trick with the utests or the tests u can buy at local stores.. if you drink enough water it usually clean out your system well enough to not show up on the test.. its worked for me on multiple occasions maybe once or twice and my friend does it everytime before he gets drug tested and he passes everytime... also id suggest workingout and trying to sweat a lot to try to get rid of some the thc in your system .. and from what i've research of detox.. theyre mostly water and then you fill them with more water.. but thats only what i've heard about it... and i would like to hear how you did? since this was a month ago

 

faint pink=pink=pass!
