It is difficult to get an accurate reading from urine that is two weeks old depending on the type of testing accomplished. In a 24 hour urine study, the urine must be fresh and refrigerated. Often, after a week, the urine will begin to grow bacteria colonies that obscure testing results.

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 :)
