either you should put in in the fridge or keep it at room tempature. If you put it in the fridge it slows down the dilution process. if your trying to pass a drug test i recommend taking 3 to 4 asprin and drinking alot of water.
sometimes!
If you deliver a diluted sample, they'll flunk you just for the dilution.
Nope!
A diluted urine drug test is one where the sample was diluted. It happens in two ways--you drank too much water to make yourself pee (DOT's standard says drink no more than 40 ounces of water), or you put water in your sample after you peed it out.A negative diluted test says "no drugs in this sample passed the test thresholds, but it was diluted so there MIGHT be drugs in here." Basically, a diluted negative is a test failure.
Diluted urine can cause a violation of probation. Diluted urine indicates that the urine has been tampered with to alter test results.
only if you are stupid enought to do that and risk jail
It is very common for a person who is menstruating to contaminate a urine sample. Of course, contaminated urine samples are very common in general.
to diluted the substance that present in the urine
If temperature is being used to verify that the urine came from the correct person the temperature of the sample is an indicator that the urine is/may not be a fresh/valid sample...if the temperature is lower than expected.
A freshly collected sample of urine will be near body temp. A bottle of someone else's urine (that does not do drugs) in your pocket will not be as warm. If the temp of a sample is very low, it is not considered to be a valid sample from THAT person.
Pissing in a bottle and putting it in the fridge, YOU IDIOT
A urine sample usually lasts up to 7 days if frozen.
