Idiots on here. The person is asking as obviously they are trying to use someone else's urine to pass a drug test. If a 50 year old man turns in urine that is determined to be from a 16 year old man, and they can tell, that means the test is failed.


If the urine is old will it test posative for drugs if urine is really clean of drugs but just old?

no... but, drug tests show how old the urine is and the urine is always tested with a thermometer to make sure that it is YOUR body temp... the best way to pass a urine test is to know how long drugs will be in your system dont smoke weed one month before a drugs test dont take exstacy, cocaine, ketamine etc 1-2 weeks before a drugs test... LSD on the other hand (my specialist subject) cannot be traced after 6 hours of taking it... NO drugs tests test for acid :) hope this helps :)

Can you use 3 day old urine for a lab test?

No, three day old urine will probably not be useful for a lab test. Urine should be as recent as possible - preferably less than an hour old when tested. The age of the urine will affect the results differently depending on the type of test(s) being performed. If a test cannot be performed immediately, urine should be refrigerated (but not frozen).


Can old urine be used in a drug test?

Yes, but only if it has been freezedried and reconstituted within 2 hours before the test. Urine generally is of no use once it has been exposed to the air. It's only good if you don't allow it time & atmosphere to spoil. Anomal urine can also be used, and is undetectable, as they don't test for source, but only what is in it.
