How much urine is required in a drug test?

Answer 1

For a DOT test 45ml. For a drug free workplace test 30ml. If you are doing an immediate test enough so it can be read on the temperature gauge and then the test is to be put inside cup, then urine soaks into test and test lines must all be clear enough to read. If all lines are there it is negative (this is good).

Answer 2

Depending on the test used, 1-100 mL.

Just a thought, but if you are researching ways to circumvent testing positive results on a drug test and you might be considering using urine from someone else, not a good idea. There is no convenient way to keep substitute urine at temperature, and the very first thing the testing facility will do is to test the temperature of the sample. Noting that it is either too warm or too cold, you will fail the test.

So, get clean, stay clean. It is the only way you will reliably test negative.

Answer 3

While saliva drug tests are becoming increasingly popular, there is still some confusion about how they work. One of the most common questions is how much saliva is needed for an accurate test. The answer depends on the type of drug being tested for. For instance, marijuana can be detected in saliva for up to 72 hours after use, so a small sample is all that is needed. However, other drugs, such as amphetamines and cocaine, are only detectable for a few hours after use, so a larger sample is required. In general, most saliva drug tests require at least 2ml of saliva in order to be accurate. However, it is always best to follow the instructions provided by the testing kit to ensure an accurate result.
