What is the minimum amount of urine needed for a sample?

What happens if you put water in an at home drug test?

Test results may be false negatives. Within 2 or 3 days, these drugs are almost always undetectable. Teens also may try to “cheat” on a urine test. They might dilute their urine samples with tap or toilet water, or drink a lot of water before the test to flush drugs from their systems.

How soon should urine be tested after collection?
