..it's the old school method that lasted for many years and may even still work sometimes, but a lot of these labs also test for conflict
pass/fail.
Meaning if they get conflicting results they get another lab to test it for non drug related anomalies, white blood cell counts, hormones and such, if that happens and you used your child's urine a lot of times they can prove it... science IDK

,,, just saying it could get you in more trouble than its worth.
Bottom line detox for 30 days and you'll pass any piss test.
I know it's all jokes, but I'm sure some folks really don't know about that
these days.
